Hello,

I read on https://forum.qiime2.org/t/evident-effect-size-and-power-calculations-for-microbiome-community-data/23146/8

"The power analysis assumes that a new experimental design will have equal number of samples from each of the groups."

Regarding the quote above, does that mean that the power analysis results reflect the power of an experimental design with equal sample size per group (eg group A n=10, group B, n=10, group C n=10)? If we input data into Evident from an experiment with unequal sample sizes (eg group A n=2, group B, n=5, group C n=10), would the Evident output reflect the power based on the sample sizes of the data that was input?

thank you for your time.
