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

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
ON.cor
Pre-specified correlation for a pair of ordinal-normal variables.
##### Value

• A tetrachoric correlation coefficient.

• corr.nn4on
##### Examples
corr.nn4on(c(0.33, 0.66), 0.22)
