StatsQCDF
StatsQCDF (q, r, c, df)
The StatsQCDF function returns the value of the Q cumulative distribution function for r the number of groups, c the number of treatments, and df the error degrees of freedom (f = rc (n -1) with sample size n).
Details
The Q distribution is the maximum of several Studentized range statistics. For a simple Tukey test, use r =1.
