pwr_anova_unbalanced: Power and sample size to unbalanced ANOVA.
In gilberto-sassi/power:

pwr_anova_unbalanced computes the power and the sample size to unbalanced ANOVA.

1 2	pwr_anova_unbalanced(group_means, size_means, mean, sigma, sig_level = 0.05)

`group_means`	vector where each entry is the mean of the treatment
`size_means`	vector where each entry is the sample size for each treatment
`mean`	population and general mean
`sigma`	populational standard deviation
`sig_level`	significance level (Type I error probability)

pwr_anova_unbalanced returns a list with the following components:

group_means: vector where each entry is the mean of the treatment
size_means: vector where each entry is the sample size for each treatment
sigma: population standard deviation
sig_level: significance level
power_sampleSize: A tibble with number of observations n, N is the sample size and power pwr
