bounds.corr.GSC.NN: Computes the approximate lower and upper bounds of the correlation matrix entries for the continuous pairs

Description

This function calculates the approximate lower and upper bounds for all continuous pairs by the method in Demirtas and Hedeker (2011).

Usage

bounds.corr.GSC.NN(pmat)

Arguments

pmat

a n2x4 matrix where each row includes the four coefficients (a,b,c,d) of the Fleishman's system.

Value

Returns a list with two components

min

lower correlation bound matrix

max

upper correlation bound matrix

Details

The approximate correlation bounds are computed via the 'Generate, Sort, and Correlate' (GSC) technique, proposed by Demirtas and Hedeker (2011).
