"WebPERMANOVA Steps: Calculate an F ratio comparing \(F \sim \frac{SS_{within groups}}{SS_across groups}\), where \(SS\) means adding up the sum of the squares of the distances. Test whether \(F\) is smaller than expected by chance by permuting the original objects. Groups should be defined a priori and not derived from distances. " - Permanova in phyloseq
