In CA3variants: Three-Way Correspondence Analysis Variants

Summary of three-way correspondence analysis results

Description

This function prints the summary of the results of three-way symmetrical or non-symmetrical correspondence analysis. In particular it gives information on core and squared core and on the explained inertia when reducing dimensions.

Usage

## S3 method for class 'CA3variants'
summary(object, digits=3, ...)

Arguments

object	The name of the output of the main function CA3variants.
digits	The input parameter specifying the digital number. By default, digits = 3.
...	Further arguments passed to or from other methods.

Value

The value of output returned in short depends on the kind of three-way correspondence analysis variant performed. It gives the core table, the squared core table, the explained inertia, the total inertia and its proportion.
