ClusterRandSSAdj: Small Sample Adjustment of Cluster Randomized Trial
A set of functions to apply 'HC3' (FIRORES) and 'HC2' (ROOT) sandwich estimators to make small-sample
adjustments to standard errors of Generalized Linear Model statistics used to analyze cluster
randomized trial data. The functions in the 'ClusterRandSSAdj' package make small-sample adjustments
to Generalized Linear Model parameter estimates, least squares means and pair-wise comparison of least
squares means, Type III tests, and estimates from linear combinations of Generalized Linear Model
parameters. For more details see Ford (2017) <doi:10.1002/bimj.201600182> and Westgate (2022) <doi:10.1177/17407745211063479>.
