Hi,
I am trying to compare the person fit statistics between two models with the same data, but a different dimensional structure (a 1D model compared to a 3D model). When I ask for person fit statistics along with the WLE estimates (by specifying show cases !estimates=wle,pfit=yes), ConQuest produces what looks like a MNSQ statistic accompanying the unidimensional estimates, and a t-statistic for the multidimensional estimates. Is this correct? And if so, is there any way to get a common fit statistic, short of performing the complex calculation (Wang & Chen, 2005) myself? I have attached the WLE estimates from each model. Any help is appreciated.
Thanks,
Courtney
