OrdNor (version 2.2.3)

LimitforON: Finds the feasible correlation range for a pair of ordinal and normal variable

Description

The function computes the lower and upper bounds of a pairwise correlation between an ordinal and a normal variable via the method of Demirtas and Hedeker (2011).

Usage

LimitforON(pvec1)
Limit_forON(pvec1) #deprecated

Arguments

pvec1

A vector of marginal probabilities for an ordinal variable of the pair.

Value

A vector of two elements. The first element is the lower bound and the second element is the upper bound.
