summary.PCAmix: Summary of a 'PCAmix' object

In PCAmixdata: Multivariate Analysis of Mixed Data

Description

This is a method for the function summary for objects of the class PCAmix.

Usage

## S3 method for class 'PCAmix'
summary(object, ...)

Arguments

object	an object of class PCAmix obtained with the function PCAmix or PCArot.
...	further arguments passed to or from other methods.

Value

Returns the matrix of squared loadings. For quantitative variables (resp. qualitative), squared loadings are the squared correlations (resp. the correlation ratios) with the scores or with the rotated (standardized) scores.
