Identifiability

By | May 30, 2017

This app visualizes the trade-off between the parameters of a non-identifiable basic local independence model (BLIM).

Classical and Bayesian parameter estimation

By | May 30, 2017

This app demonstrates classical and Bayesian parameter estimation methods for probabilistic knowledge structures.

Parameter estimation

By | May 30, 2017

This app uses three procedures to estimate the parameters for a data set and a knowledge structure specified by the user.

The Skill mApp

Local independence

By | April 6, 2017

This app exemplifies the local independence assumption of the basic local independence model (BLIM). This assumption is used to calculate the probability P(R|K) of a response pattern R given the knowledge state K. First the user learns the empirical interpretation of the model parameters. Next, an example with five items demonstrates the difference between correct responses and mastered… Read More »
