runPostHoc: Perform Post-Hoc Testing

In tpq/propr: An R package to calculate proportionality and other measures for compositional data

Perform Post-Hoc Testing

Description

After running an ANOVA of more than 2 groups, it is useful to know which of the groups differ from the others. This question is often answered with post-hoc testing. This function implements post-hoc pairwise differential proportionality analyses for more than 2 groups.

Usage

runPostHoc(object)

Arguments

object

A propd object.

Details

The ANOVA p-values are adjusted once (column-wise) during the original multi-group analysis. The post-hoc p-values are adjusted once (row-wise) for the number of post-hoc tests. The post-hoc adjustment is p times the number of post-hoc tests.

Please note that a significant post-hoc test without a significant ANOVA test is not significant!

Value

A propd object.
