print.soc.mca: Print soc.ca objects

In soc.ca: Specific Correspondence Analysis for the Social Sciences

Description

Prints commonly used measures used in the analysis of multiple correspondence analysis

Usage

## S3 method for class 'soc.mca'
print(x, ...)

Arguments

x	is a soc.ca class object
...	further arguments are ignored

Value

Active dimensions is the number of dimensions remaining after the reduction of the dimensionality of the analysis.

Active modalities is the number of modalities that are not set as passive.

Share of passive mass is the percentage of the total mass that is represented by the passive modalities.

The values represented in the scree plot are the adjusted inertias, see variance

The active variables are represented with their number of active modalities and their share of the total variance/inertia.
