FAQ
How do I know if I need multilevel modeling?
If your data has clustering (students in schools, patients in hospitals, repeated measures) or hierarchical structure, multilevel models are essential. I'll assess your data structure and recommend the appropriate approach.
Can you handle longitudinal growth curve models?
Absolutely! I specialize in growth curve modeling, change over time analysis, and trajectory modeling. This includes linear, quadratic, and piecewise growth models with individual and group-level predictors.
What software do you recommend for multilevel analysis?
I work with MPlus, R (lme4, nlme), SPSS Mixed Models, Stata xtmixed. I'll recommend MPlus as the best option based on your model complexity, data size, and institutional software availability.
