Abstract: polycorr estimates each correlation by the two-step method. Thresholds come from the margins and each correlation from its own pair, using listwise or pairwise deletion. polypml instead estimates all thresholds and correlations jointly, using every observed value.

Language: Stata
Requires: Stata version 14
