Abstract:
|
Two more statistical software packages, MPLUS and WinBUGS, were tested as a continuation of a previous study of analysis method/software robustness in the analysis of clustered data. We want to evaluate robustness in the context of a randomized complete block design, where each "plot" is a small group of children at the same nursery school and a series of measurements of each child are made. We constructed a series of super populations in which the standard assumptions of hierarchical (mixed effects) linear models were violated. The results were compared with HLM, SUDAAN, PROC MIXED and a semi-parametrical analysis of variance procedure we tested before.
