Abstract

The objective of the study is to determine the ability of estimation stability and item parameter characteristics based on the use of logistic models. The data used are simulated data which generated using WINGEN, as much as 1000 participants sample size with length of test of 40 items. Further estimation is done using 1PL, 2PL, and 3PL model as many as ten replication. Based on result analysis, it can be seen that the parameter capability and parameter characteristics of items produced with the 1PL model, more suitable estimated with the 1PL model, the 2PL model, more suitable estimated with the 2PL model, and the 3PL model, more suitable estimated with the 3PL model. These matches can be seen from median score of the estimated correlation data and the original data generated by WINGEN. Therefore, the ability and the characteristic parameters need to pay attention to the logistic parameter model used, to make the estimation as accurate as possible.
