I have used Ex. 5.5 for conventional Samejima modeling of a nine-item test administered over 12 sessions. Because this is a clincal trial, there is nonrandom attrition so I feel most comfortable analyzing the data separately by sessions. I have three questions regarding version 6.11 output which I gather produces different output from previous versions. 1. Why does the output entitled "Chi-Square Test for MCAR under the Unrestricted Latent Class Indicator Model" appear on some outputs and not on others, apparently at random? 2. Why is there no CFI or TL descriptive output? I can understand why there is no RMSEA. 3. The results at week 0 for the Binary and Ordered Categorical Likelihood ratio Chi-squares are as follows: Value 1962.712 Degrees of Freedom 1952731 P-Value 1.0000 These appear strange (similar values are found across the 12 sessions). |
