BILOG-MG features a dialog-box user interface toassist first-time users or occasional users with writing such a commandfile. BILOG-MG handles multiple groups， standard deviations， and handling ofmultiple groups Performs item analysis and scoring of any number of subtests orsubscales Non-equivalent groups equating Vertical equating of test forms Differential item functioning (DIF) Detection and correction for parameter trends over time (DRIFT) Calibration and scoring of tests in two-stage testing procedures Estimation of latent ability or proficiency distributions Provision for items inserted in tests to estimate item statistics， wrong， BILOG-MG3 研究阐明軟體 Research ldquo;變體項目） 項目擬合統計 理論和經驗可靠性 推定測試表的信息曲線和可靠性 推定測試表的信息曲線和可靠性 詳細的在線幫助文檔 包罗完整用戶手冊的PDF文件 系統要求Windows 95， and test informationcurves to BILOG-MG. The plots may be saved in the Windows Metafile format (WMF)and are then easily included in applications such as MS Word. Although the programs are commanddriven (an analysis is specified by creating a command file with theincluded editor)。

98，www.aepnet.com， and XP.Extensive online Help has been added， covering almost completely thenewly edited book that combines all four programs in one volume. Annotated program input and output can be found throughout the onlineHelp system and the new manual. A graphic module adds itemcharacteristic curves， vertical equating， and it includes a simplified formsspecification. Both normal and empirical latent distributions can bespecified by the user. Bayes estimation of scale scores can be donewith a group-specific or global prior. It computes information curvesand statistics by form as well as by test. The user can perform similarcomputations for any arbitrarily selected subset of items. The numerousexamples include a folder with all the original BILOG examples andtheir equivalent command files for BILOG-MG.
