WaterDOM statistics

H0: all groups are equal (p-value>0.05)
H1: at least one group is different (p-value<0.05)
Type I error: reject a true H0 = accept a false H1
Type II error: reject a true H1 = accept a false H0
Statistical power: probability to reject a false H0 = 1-p(type II error)
α:
k = 106 (number of variables)
FWER: probability of doing at least one type I error doing k tests
FWER: 1-(1-α)^k = 1-(1-0.05)¹⁰⁶ = 0.9956478669819241
Bonferroni method: set α to α/k to keep FWER = 0.05
