class sdt_metrics.loglinear_bppd(methodname, add_prob_method=False)¶

loglinear B’‘d: nonparametric measure of response bias

Corrects boundary problems with bppd. by applying Hautus’s [1] loglinear transformation to counts before calculating bppd. For more information see the Analysis of loglinear_bppd

Note

This metric cannot be calculated from probabilities
