Description

This function provides a tool for the interpretation of the results of fpcad or fmdsd function.

Usage

1
interpret(x, nscore = 1:3, moment = "mean")

Arguments

x

object of class fpcad or fmdsd.

  • fpcad: see interpret.fpcad

  • fmdsd: see interpret.fmdsd

nscore

numeric vector. Selects the columns of the data frame x$scores to be interpreted.

Warning: Its components cannot be greater than the nb.factors argument in the call of the fpcad function.

moment

characters string. Selects the moments to cross with scores:

  • "mean" (means)

  • "sd" (standard deviations)

  • "cov" (covariances)

  • "cor" (correlation coefficients)

  • "skewness" (skewness coefficients)

  • "kurtosis" (kurtosis coefficients)

  • "all" (for univariate densities only. It simultaneously considers means, standard deviations, variances and skewness and kurtosis coefficients)

Value

Returns a list including:

pearson

matrix of Pearson correlations between selected scores and moments.

spearman

matrix of Spearman correlations between selected scores and moments.
