R: Perform Post-Hoc Testing

posthoc {propr} | R Documentation

## 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

    posthoc(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 never significant!

### Value

A `propd` object.
