Multilevel-multidimensional Item Response Theory(IRT) models have been developed to address the nested structure of item response data from the complex sampling or repeated measures designs(e.g.,Fox,2
Mallows defined the Cp statistic with an associated Cp plot to be used in model selection in regression analysis.The deviance plot is an extension of this idea,where the loss,expressed in residual sum

Many intervention programs,such as the PAX Good Behavior Game(PAX) program implemented in Manitoba province-wide schools,often have multiple outcome variables(e.g.,Emotional Symptoms,Conduct Problems,
Piecewise growth mixture modeling(PGMM) can be used to investigate growth and change of subpopulations consisting of distinct developmental phases(Muthén,2008).
Diagnostic Classification Models(DCMs) classify examinees into attribute mastery profiles and have useful instruction and assessment implications for students and educators.
