It provides user-friendly interfaces to compute various equating applications. Equating methods (mean, linear, and equipercentile method), smoothing methods (log-linear, beta-binomial and cubic spline method), standard error estimation using bootstrap method, and truncation are included for different choice of the group design. It is being implemented using Windows system programming in C++.Teaching AssistantThe University of IowaMathematics Department 08/1999 – 12/2004 Taught in dependent discussion sections for calculus coursesManaged data using SASPROGRAMMING LANGUAGES AND SOFTWARE EXPERIANCES: Programming SkillsCOBOL, FORTRAN,C, C++, C#, JavaScientific programming in Mathematica and MatlabSoftware Proficiency – Advanced level inStatistics software packages: SPSS, SAS, R, WinBUGS SEM package: Mplus, SASOS: All Window versions, Macintosh, Linux, Unix Microsoft Office Suite: Excel, Word, PowerPoint, Access, OneNoteWeb programming software: MS FrontPageMS Visual Studio .NET/MS Visual Studio 2010BILOG-MG3, Winsteps, PASCALE RESEARCH AND PAPERS ResearchThe effect to student’s performance based on the order of clerkship programs (prediction analysis)The effect of human judgement to student’s clinical performanceReliability analysis in OSCE using generalizability theoryComparison between the traditional equipercentile equating methods and a conditional equating method (local equating method) under random group designThe effect of equating methods on forms with different difficulty level.Modified statistical model to robust for erasure detectionComparable statistics of erasure detection between CBT and PBTComparison among IRT true-score, IRT observed-score equating methods, and a conditional equipercentile equating method under random group designA conditional equating method under common-item nonequivalent groups designModified circle arc equating method for small sample size examMultidimensional IRT Item parameter estimationEffect on item security by item exposureItem drift analysis comparisonItem security breach: detecting cheat & item harvestStructural Equation Modeling using measurement model PublicationsS.
