Rasch Model Workshop With Prof Bond
Day 3 The basic tenet of Rasch model posits that the probability of a specified response (e.g. right/wrong answer) is modeled as a function of person and item parameters. Specifically, in the simple Rasch model, the probability of a correct response is modeled as a logistic function of the difference between the person and item parameter. In the morning, participants were exposed to the concepts of "dochotomous" and "polytomous" measures.
