Abstract: sreg provides estimation and inference for average treatment effects in stratified randomized experiments. It implements design-specific treatment-effect estimators and variance estimators for matched pairs, general k-tuple designs, large strata of potentially unequal sizes, and designs combining small and large strata. The package accommodates multiple treatments, individual- and cluster-level treatment assignment, and optional linear covariate adjustment. It reports treatment effects relative to control, standard errors, test statistics, p-values, and asymptotic confidence intervals. Companion commands generate experimental data and plot estimated treatment effects.
