CA3variants (version 3.3.1)

summary.CA3variants: 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 CA3variants
summary(object, digits=3, ...)

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.

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.
