corr.nn4on {PoisBinOrdNor}

Finds polyserial correlation for given the correlation for an ordinal-normal pair.

Description

This function computes the polyserial correlation given the specified correlation for a pair of ordinal and normal variables (point-polyserial correlation).

Usage

corr.nn4on(p, ON.cor)

Arguments

p

A vector of probabilities for an ordinal variable. The i-th element of the pvec is the cumulative probability defining the marginal distribution of the ordinal variable. If the variable has k categories, the i-th element of p will contain k-1 probabilities. The k-th element is implicitly 1.

ON.cor

Pre-specified correlation for a pair of ordinal-normal variables.

Value

A tetrachoric correlation coefficient.
