HyunhFeldtEpsilon

HyunhFeldtEpsilon() is a measure of sphericity created by
gg58;textualsuperb. The original measure was biased
and therefore, hf76;textualsuperb produced a revised version
(note that the 1976 paper contained typos that were uncorrected
in SPSS; l91;textualsuperb)

Computes standard error and confidence interval of various descriptive statistics under
various designs and sampling schemes. The main function, superbPlot(), return a plot. superbData()
returns a dataframe with the statistic and its precision interval so that other plotting package
can be used. See Cousineau and colleagues (2021) <doi:10.1177/25152459211035109>
