Truly Longitudinal Models
Longitudinal count models for repeated event totals, rates, and frequencies.
MERF, REEMforest, REEMCatBoost, and MECB are available for smaller panels, but Preview Data Readiness will disable them when the estimated work exceeds the 500,000 interactive guardrail.
Use the checked defaults for normal runs; only add the slower mixed-effects paths when the preview keeps them available.
Optional Baselines
Lighter benchmark runs using the longitudinal-count models available in this build.
Classical Count Panel Models
Statsmodels-backed GEE and Poisson mixed-model paths for repeated count outcomes.
Poisson GEE is included in the balanced default. Negative Binomial GEE and Poisson GLMM are available for overdispersed or subject-specific analyses and may take longer on larger panels.
