Description

Compute measures of fit for biplot.

For an object of class CVA:

axis.predictivity

fit measure of each individual axis.

class.predictivity

fit measure for each class mean.

within.class.axis.predictivity

fit measure for each axis based on values expressed as deviations from their class means.

within.class.sample.predictivity

fit measure for each sample expressed as deviation from its class mean.
