" MSP has not been updated the last 12 years. Investigating IIO is possible using the R-package 'mokken'.
The method for investigating IIO has been described in Ligtvoet, Van der Ark, Te Marvelde, & Sijtsma (2010; Educational and Psychological Measurement).
- The software has been described in Van der Ark (2007; Journal of Statistical Software), Van der Ark (2012; Journal of Statistical Software), Van der Ark (2010; unpublished report "Getting Started with Mokken scale Analysis in R").
R can be downloaded free of charge from cran.r-project.org/ "
目前還是只能用R軟體來分析，這幾天會盡快閱讀作者所提到這幾篇文獻。
what is "IIO"?
回覆刪除"IIO" stands for invariant item ording.
回覆刪除IIO is equivalent to the Non-intersection of the item response function (IRF).
An invariant item ordering also may be interpreted as support for a theory about item difficulty.

回覆刪除但這好像不是您最重要的議題
