介紹 IRTPRO
SSI 開發了一個新的軟體,稱為 IRTPRO,這是一項在目前的技術尖端的產品。該方案已於微軟的 Windows平台的 Windows7,Vista和 XP操作系統上經過廣泛的測試。
IRTPRO 數值引擎的重要區塊已同時並行運行多個核心。
IRTPRO 發展得到了NIH的SBIR計劃合同HHSN-2612007-00013C 題為:
MEDPRO:開發項目反應理論成果和行為測量軟體。
Technical Description
IRTPRO imports data from a variety of statistical software packages as well as importing data from fixed format data (.fixed), comma-separated (.csv), tab-delimited (usually .txt), and Excel (.xls) files. Whatever the original format, the imported data are saved to an IRTPRO data file with extension .ssig that is displayed visually as a spreadsheet, similar in appearance to an Excel spreadsheet.
IRT models for which item calibration and scoring are implemented in IRTPRO are based on unidimensional and multidimensional [confirmatory factor analysis (CFA) or exploratory factor analysis (EFA)] versions of the following widely used response functions:
o Two-parameter logistic (2PL) [with which equality constraints includes the one-parameter logistic (1PL)
o Three-parameter logistic (3PL)
o Graded
o Generalized Partial Credit
o Nominal
Winsteps 是Windows 介面的軟體,用 Rasch-Model 的很多應用幫助,特別是在教育測試,看法調查和等級規模分析的區域內。
Rasch analysis是一種方法,能夠獲得客觀的、基本的、由隨機觀察有序類別的反應的線性措施(合格的標準誤差和質量控制符合統計)。Georg Rasch,丹麥數學家,於 1953年制定本辦法,分析了一系列的反應,閱讀測驗(Rasch G, Probabilistic Models for Some Intelligence and Attainment Tests, Chicago: MESA Press, 1992, withinstructive Foreword and Afterword by B.D. Wright)
在丹麥語Rasch發音類似英語單詞rash,在德國聽起來像英語raa-sch。德國發音,raa-sch,是為了避免誤解。人與項目總原始分數被用來估計線性措施。 Rasch模式條件下,這些措施是項目免費(項目分配免費)和人的自由(人分配免費)。因此,該措施相當於統計的項目-無論是哪個人(來自同一人口)進行了分析,對其中無論哪個項目(來自同一人口)進行了分析。分析數據的響應級別表明在何種程度上實現這些理想在任何特定的數據集。
在 Winsteps,Rasch模式實施包括Georg Rasch dichotomous, Andrich "rating scale",Masters "partial credit", Bradley-Terry "paired comparison",Glas "success model",Linacre "failure model"和most combinations of these models。其他如binomial trials和Poisson也可以分析anchoring (fixing)的結構,以符合反應的反應模型。 (如果您有特殊需要,請讓我們知道,Winsteps不斷增強。)
該估計方法是JMLE,“Joint Maximum Likelihood Estimation”,與初始值開始提供PROX是Normal Approximation Algorithm”。
