Effect size for dependent samples ANOVA
Compute an AKP-type effect size for dependent sample ANOVA
wmcpAKP(x, tr = 0.2, nboot = 200)
x |
data frame in wide format (no missing values allowed) |
tr |
trim level for the means. |
nboot |
number of bootstrap samples. |
The computation is based on a modification of the Algina-Keselman-Penfield effect size for J dependent samples.
