LimitforON function

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

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).

LimitforON(pvec1)
Limit_forON(pvec1) #deprecated

Arguments

• pvec1: A vector of marginal probabilities for an ordinal variable of the pair.

Returns

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