scripts default iconOptiPt (Scripts) Publisher's description

OptiPt is a function for fitting and testing (multi-attribute) probabilistic choice models

OptiPt is a function for fitting and testing (multi-attribute) probabilistic choice models, especially the Bradley-Terry-Luce (BTL) model (Bradley & Terry, 1952; Luce, 1959), elimination-by-aspects (EBA) models (Tversky, 1972), and preference tree (Pretree) models (Tversky & Sattath, 1979).

Features of OptiPt are:
-- easy model specification
-- high-precision parameter estimation
-- goodness of fit test
-- covariance matrix of the parameter estimates
