raschtest estimates the parameters of a Rasch model. The estimation method can be chosen between conditional maximum likelihood (CML), marginal maximum likelihood (MML) and generalized estimating equations (GEE). raschtest offer a set of tests, to valuate the fit of the data to the Rasch model, or detect non homogeneous items (Andersen Z test, First order test (Q1, R1c, R1m, or Wright Panchapakesan), U test, Split test) and indexes (OUTFIT and INFIT per items or per individuals). Several graphical representations can be easily obtained: comparison of the observed a nd theoretical Item Characteristic Curves (ICC), Map difficulty parameters/Scores, results of the split tests, and information function. Stata 7 users should employ raschtestv7. The gllamm routine also must be installed (ssc install gllamm, replace).
