summary.pordlogist: Summary Method Function for Objects of Class 'pordlogist'

In OrdinalLogisticBiplot: Biplot representations of ordinal variables

Description

This function shows a summary of the principal results for the estimation for individuals and variables, like number of observations, the number of iterations, the covariances matrix, some Pseudo R-squared indices with the correct classification percentage of each regression and the logLikelihood with "Estimate coefficients", "Std. Error", "z value" or "Pr(>|z|)" values.

Usage

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

Arguments

object	This parameter keeps 'pordlogist' object for a variable.
...	Additional parameters to summary.

Details

This function is a method for the generic function summary() for class "pordlogist". It can be invoked by calling summary(x) for an object x of the appropriate class.
