A class for simulation results rates.
groupsThe number of groups. Is an integer vector of length 1.
directionUpperLogical. Specifies the direction of the alternative, only applicable for one-sided testing, default is TRUE which means that larger values of the test statistics yield smaller p-values.
normalApproximationLogical. Describes if a normal approximation was used when calculating p-values.
Default for means is FALSE and TRUE for rates and hazard ratio.
