1 What is a CVA biplot

Consider a data matrix \(\mathbf{X}:n \times p\) containing data on \(n\) objects and \(p\) variables. In addition, a vector \(\mathbf{g}:n \times 1\) contains information on class membership of each observation. Let \(G\) indicate the total number of classes. CVA is closely related to linear discriminant anlaysis, in that the \(p\) variables are transformed to \(p\) new variables, called canonical variates, such that the classes are optimally separated in the canonical space. By optimally separated, we mean maximising the between class variance, relative to the within class variance. This can be formulated as follows:

Let \(\mathbf{G}:n \times G\) be an indicator matrix with \(g_{ij} = 0\) unless observation \(i\) belongs to class \(j\) and then \(g_{ij} = 1\). The matrix \(\mathbf{G'G}\) is a diagonal matrix containing the number of observations per class on the diagonal. We can form the matrix of class means \(\bar{\mathbf{X}}:G \times p = (\mathbf{G'G})^{-1} \mathbf{G'X}\). With the usual analysis of variance the total variance can be decomposed into a between class variance and within class variance:

\[ \mathbf{T} = \mathbf{B} + \mathbf{W} \]

\[ \mathbf{X'X} = \mathbf{\bar{\mathbf{X}}'C \bar{\mathbf{X}}} + \mathbf{X' [I - G(G'G)^{-1}C(G'G)^{-1}G'] X} \]

The default choice for the centring matrix \(\mathbf{C = G'G}\) leads to the simplification

\[ \mathbf{X'X} = \mathbf{\bar{\mathbf{X}}'G'G \bar{\mathbf{X}}} + \mathbf{X' [I - G(G'G)^{-1}G'] X}. \]

Other options are \(\mathbf{C = I}\) and \(\mathbf{C} = (\mathbf{I}_G - \frac{1}{G}\mathbf{11'})\). To find the canonical variates we want to maximise the ratio

\[ \frac{\mathbf{m'Bm}}{\mathbf{m'Wm}} \]

subject to \(\mathbf{m'Wm} = 1\). It can be shown that this leads to the following equivalent eigen equations:

\[ \mathbf{W}^{-1}\mathbf{BM} = \mathbf{M \Lambda} \tag{1} \]

\[ \mathbf{BM} = \mathbf{WM \Lambda} \]

\[ (\mathbf{W}^{-\frac{1}{2}} \mathbf{B} \mathbf{W}^{-\frac{1}{2}}) \mathbf{M} = (\mathbf{W}^{-\frac{1}{2}} \mathbf{M}) \mathbf{\Lambda} \]

with \(\mathbf{M'BM}= \mathbf{\Lambda}\) and \(\mathbf{M'WM}= \mathbf{I}\).

Since the matrix \(\mathbf{W}^{-\frac{1}{2}} \mathbf{B} \mathbf{W}^{-\frac{1}{2}}\) is symmetric and positive semi-definite the eigenvalues in the matrix \(\mathbf{\Lambda}\) are positive and ordered. The rank of \(\mathbf{B} = min(p, G-1)\) so that only the first \(rank(\mathbf{B})\) eigenvalues are non-zero. We form the canonical variates with the transformation

\[ \bar{\mathbf{Y}} = \bar{\mathbf{X}}\mathbf{M}. \]

To construct a 2D biplot, we plot the first two canonical variates \(\bar{\mathbf{Z}} = \bar{\mathbf{X}}\mathbf{MJ}_2\) where \(\mathbf{J}_2' = \begin{bmatrix} \mathbf{I}_2 & \mathbf{0} \end{bmatrix}\). We add the individual sample points with the same transformation

\[ \mathbf{Z} = \mathbf{X}\mathbf{MJ}_2 \] where \[ \mathbf{J}_2 = \begin{bmatrix} \mathbf{I}_2\\ \mathbf{0} \end{bmatrix}. \] Interpolation of a new sample \(\mathbf{x}^*:p \times 1\) follows as \({\mathbf{z}^*}':2 \times 1 ={\mathbf{x}^*}' \mathbf{MJ}_2\). Using the inverse transformation \(\mathbf{x}' = \mathbf{y}'\mathbf{M}^{-1}\), all the points that will predict \(\mu\) for variable \(j\) will have the form

\[ \mu = \mathbf{y}'\mathbf{M}^{-1} \mathbf{e}_j \]

where \(\mathbf{e}_j\) is a vector of zeros with a one in position \(j\). All the points in the 2D biplot that predict the value \(\mu\) will have

\[ \mu = \begin{bmatrix} z_1 & z_2 & 0 & \dots & 0\end{bmatrix}\mathbf{M}^{-1} \mathbf{e}_j \]

defining the prediction line as

\[ \mu = \mathbf{z}_{\mu}' \mathbf{J}_2 \mathbf{M}^{-1} \mathbf{e}_j. \]

Writing \(\mathbf{h}_{(j)} = \mathbf{J}_2 \mathbf{M}^{-1} \mathbf{e}_j\) the construction of biplot axes is similar to the discussion in the biplotEZ vignette for PCA biplots. The direction of the axis is given by \(\mathbf{h}_{(j)}\). To find the intersection of the prediction line with \(\mathbf{h}_{(j)}\) we note that \[ \mathbf{z}'_{(\mu)}\mathbf{h}_{(j)} = \| \mathbf{z}_{(\mu)} \|^2 \| \mathbf{h}_{(j)} \|^2 cos(\mathbf{z}_{(\mu)},\mathbf{h}_{(j)}) = \| \mathbf{p} \|^2 \| \mathbf{h}_{(j)} \|^2 \] where \(\mathbf{p}\) is the length of the orthogonal projection of \(\mathbf{z}_{(\mu)}\) on \(\mathbf{h}_{(j)}\).

Since \(\mathbf{p}\) is along \(\mathbf{h}_{(j)}\) we can write \(\mathbf{p} = c\mathbf{h}_{(j)}\) and all points on the prediction line \(\mu = \mathbf{z}'_{\mu}\mathbf{h}_{(j)}\) project on the same point \(c_{\mu}\mathbf{h}_{(j)}\). We solve for \(c_{\mu}\) from \[ \mu = \mathbf{z}'_{\mu}\mathbf{h}_{(j)}=\| \mathbf{p} \|^2 \| \mathbf{h}_{(j)} \|^2 = \| c_{\mu}\mathbf{h}_{(j)} \|^2 \| \mathbf{h}_{(j)} \|^2 \]

\[ c_{\mu} = \frac{\mu}{\mathbf{h}_{(j)}'\mathbf{h}_{(j)}}. \] If we select ‘nice’ scale markers \(\tau_{1}, \tau_{2}, \cdots \tau_{k}\) for variable \(j\), then \(\tau_{h}-\bar{x}_j = \mu_{h}\) and positions of these scale markers on \(\mathbf{h}_{(j)}\) are given by \(p_{\mu_{1}}, p_{\mu_{2}}, \cdots p_{\mu_{k}}\) with \[ p_{\mu_h} = c_{\mu_h}\mathbf{h}_{(j)} = \frac{\mu_h}{\mathbf{h}_{(j)}'\mathbf{h}_{(j)}}\mathbf{h}_{(j)} \]

\[ = \frac{\mu_h}{\mathbf{e}_{(j)}' \mathbf{M'}^{-1} \mathbf{J} \mathbf{M}^{-1} \mathbf{e}_{(j)}}\ \mathbf{J}_2 \mathbf{M}^{-1} \mathbf{e}_{(j)} \]

with \[ \mathbf{J} = \begin{bmatrix} \mathbf{I}_2 & \mathbf{0}\\ \mathbf{0} & \mathbf{0} \end{bmatrix}. \]

2 The function CVA()

To obtain a CVA biplot of the state.x77 data set, optimally separating the classes according to state.region we call

biplot(state.x77) |> 
  CVA(classes = state.region) |> 
  plot()

Fitting \(\alpha\)-bags to the classes makes it easier to compare class overlap and separation. For a detailed discussion on \(\alpha\)-bags, see the biplotEZ vignette.

biplot(state.x77) |> CVA(classes = state.region) |> alpha.bags() |> 
  legend.type (bags = TRUE) |> 
  plot()
#> Computing 0.95 -bag for Northeast 
#> Computing 0.95 -bag for South 
#> Computing 0.95 -bag for North Central 
#> Computing 0.95 -bag for West

3 The function means()

This function controls the aesthetics of the class means in the biplot. The function accepts as first argument an object of class biplot where the aesthetics should be applied. Let us first construct a CVA biplot of the state.x77 data with samples optimally separated according to state.division.

biplot(state.x77, scaled = TRUE) |> 
  CVA(classes = state.division) |> 
  legend.type(means = TRUE) |> 
  plot()

Instead of adding a legend, we can choose to label the class means. Furthermore, the colour of each class mean defaults to the colour of the samples. We wish to select a different colour and plotting character for the class means.

biplot(state.x77, scaled = TRUE) |> 
  CVA(classes = state.division) |> 
  means(label = TRUE, col = "olivedrab", pch = 15) |> 
  plot()

If we choose to only show the class means for the central states, the argument which is used either indicating the number(s) in the sequence of levels (which = 4:7), or as shown below, the levels themselves:

biplot(state.x77, scaled = TRUE) |> 
  CVA(classes = state.division) |> 
  means (which = c("West North Central", "West South Central", "East South Central", 
                     "East North Central"), label = TRUE) |>
  plot()

The size of the labels is controlled with label.cex which can be specified either as a single value (for all class means) or a vector indicating size values for each individual sample. The colour of the labels defaults to the colour(s) of the class means. However, individual label colours can be spesified with label.col, similar to label.cex as either a single value of a vector of length equal to the number of classes.

biplot(state.x77, scaled = TRUE) |> 
  CVA(classes = state.division) |> 
  means (col = "olivedrab", pch = 15, cex = 1.5,
         label = TRUE, label.col = c("blue","green","gold","cyan","magenta",
                                     "black","red","grey","purple")) |>
  plot()

We can also make use of the functionality of the ggrepel package to place the labels.

biplot(state.x77, scaled = TRUE) |> 
  CVA(classes = state.division) |> 
  samples (label = "ggrepel", label.cex=0.65) |> 
  means (label = "ggrepel", label.cex=0.8) |> plot()

4 The function classify()

Classification regions can be added to the CVA biplot with the function classify(). The argument classify.regions must be set equal to TRUE to render the regions in the plot. Other arguments such as col, opacity and borders allows to change the aesthetics of the regions.

biplot(state.x77, scaled = TRUE) |> 
  CVA(classes = state.division) |>
  classify(classify.regions = TRUE,opacity = 0.2) |>

5 The functions fit.measures() and summary()

There is a number of fit measures that are specific to CVA biplots. The measures are computed with the function fit.measures() and the results are displayed by the function summary().

Canonical variate analysis can be considered as a transformation of the original variables to the canonical space followed by constructing a PCA biplot of canonical variables. The matrix of class means \(\bar{\mathbf{X}} = (\mathbf{G'G})^{-1} \mathbf{G'X}\) is transformed to \(\mathbf{\bar{X}L}\) where \(\mathbf{L}\) is a non-singular matrix such that \(\mathbf{LL'=W}^{-1}\). Pricipal component analysis finds the orthogonal matrix \(\mathbf{V}\) such that

\[ \mathbf{(L'\bar{X}'C\bar{X}L)V=V \Lambda} \]

where \(\mathbf{M = LV}\) as defined in section 1. The predicted values for the class means is given by

\[ \mathbf{\hat{\bar{X}}} = \mathbf{\bar{X}MJ}\mathbf{M}^{-1}. \]

6 Additional CVA dimensions

It was mentioned that the eigen equation (1) has \(min(p, G-1)\) non-zero eigenvalues. This implies that the CVA biplot for \(G=2\) groups, reduces to a single dimension. If we write

\[ \mathbf{M} = \begin{bmatrix} \mathbf{m}_1 & \mathbf{M}^* \end{bmatrix} \] the columns of \(\mathbf{M}^*\) forms a basis for the orthogonal complement of the canonical space defined by \(\mathbf{m}\)_1. The argument low.dim determines how to uniquely define the second and third dimensions. By default low.dim = "sample.opt" which selects the dimensions by minimising total squared reconstruction error for samples.

The representation of the canonical variates \(\bar{\mathbf{Z}} = \bar{\mathbf{X}}\mathbf{m}_1\) are exact in the first dimension, but not the representation of the individual samples \({\mathbf{Z}} = {\mathbf{X}}\mathbf{m}_1\). If we define \(\mathbf{\hat{X}} = \mathbf{XMJ}\mathbf{M}^{-1}\) with \(\mathbf{J}\) a square matrix of zeros except for a \(1\) in the first diagonal position, then the total square reconstruction error for samples is given by

\[ TSRES = tr{(\mathbf{X}-\mathbf{\hat{X}})'(\mathbf{X}-\mathbf{\hat{X}})}. \] Define \[ \mathbf{M}^{-1} = \begin{bmatrix} \mathbf{M}^{(1)}:(G-1) \times p \\ \mathbf{M}^{(2)}: (p-G+1) \times p \end{bmatrix} \]

then \(TSRES\) is minimised when

\[ \mathbf{M}^{opt} = \begin{bmatrix} \mathbf{M}_1 & \mathbf{M}^*\mathbf{V} \end{bmatrix} \]

where $\mathbf{V}$ is the matrix of right singular vectors of $\mathbf{M}^{(2)}\mathbf{M}^{(2)'}$.

@leRouxLubbe2024 discuss an alternative method for obtaining additional dimensions. When assuming underlying normal distributions, the Bhattacharyya distance can be optimised. This method is specific to the two class case and cannot be utilised to find a third dimension in a 3D CVA biplot with three classes.

7 Analysis of Distance (AoD)

Similar to the variance decomposition in CVA, analysis of distance decomposes the total sum of squared distances into a sum of squared distances between class means component and a sum of squared distances within classes component.

Consider any Euclidean embeddable distance metric \(\psi_{ij}=\psi(\mathbf{x}_i,\mathbf{x}_j)\). For a Euclidean embeddable metric it is possible to find high dimensional coordinates \(\mathbf{y}_i\) and \(\mathbf{y}_j\) such that the Euclidean distance between \(\mathbf{y}_i\) and \(\mathbf{y}_j\) is equal to \(\psi_{ij}\). Let the matrix \(\mathbf{\tilde\Psi}\) contain the values \(-\frac{1}2{}\psi_{ij}^2\) and similarly \(\mathbf{\tilde\Delta}\) the values \(-\frac{1}2{}\delta_{hk}^2\) where \(\delta_{hk}\) represent the distance between class means \(h\) and \(k\).

\[ \mathbf{T} = \mathbf{B} + \mathbf{W} \]

\[ \mathbf{1'\tilde\Psi1} = \mathbf{n'\tilde\Delta n} + \sum_{k=1}^{G} \frac{n}{n_k} \mathbf{g}_k'\mathbf{\tilde\Psi}\mathbf{g}_k \] where \(\mathbf{n}=\mathbf{(G'G)1}\). Thus, AoD differs from CVA in allowing any Euclidean embeddable measure of inter-class distance. As with CVA, these distances may be represented in maps with point representing the class means, supplemented by additional points representing the within-group variation. Principal coordinate analysis is performed, only on the \(G \times G\) matrix \(\mathbf{\tilde\Delta}\).
