WAnova:Welch's Anova from Summary Statistics
Provides the functions to perform a Welch's one-way Anova with fixed effects based on summary statistics (sample size,
means, standard deviation) and the Games-Howell post hoc test
for multiple comparisons and provides the effect size estimator
adjusted omega squared. In addition sample size estimation can
be computed based on Levy's method, and a Monte Carlo
simulation is included to bootstrap residual normality and
homoscedasticity Welch, B. L. (1951)
