Rasch模型家族中的Partial Credit Model(PCM）几乎将所有二元计分、评定量尺计分、部分计分、二项式尝试计分、泊松计次（Poisson counts）计分等类型的计量资料都涵盖在此类型的计分范畴内，因此说它是Rasch模型家族的通式，也不足为过。PCM可以适用的资料范围相当广泛，下面举例的各种资料类型，无论是教育学还是心理...

This chapter deals with the generalization of the Rasch model to a discrete mixture distribution model. Its basic assumption is that the Rasch model holds within subpopulations of individuals, but with different parameter values in each subgroup. These subpopulations are not defined by manifest indicato...
In correspondence with pertinent statistical tests, it is of practical importance to design data-sampling when the Rasch model is used for calibrating an achievement test. That is, determining the sample size according to a given type-I- and type-II-risk, and according to a certain effect of...
