pic_stat_cvar: Coefficient of variation of contrasts

In mwpennell/arbutus: Evaluate the adequacy of continuous trait models

Coefficient of variation of contrasts

Description

Calculates the coefficient of variation on a set of contrasts

Usage

pic_stat_cvar(unit.tree)

Arguments

unit.tree

a unit.tree object

Details

This test statistic is used to evaluate whether the model is sufficiently capturing the variation in rates across the tree. The coefficient of variation is the sd/mean.

The coefficient of variation of the contrasts is included as a default test statistic in the function calculate_pic_stat.

The test statistic computed from a single unit.tree can be visualized with the function pic_stat_sasr_plot.

Value

c.var the coefficient of variation of the contrasts

Examples

data(finch)
phy <- finch$phy
dat <- finch$data[,"wingL"]
unit.tree <- make_unit_tree(phy, data=dat)

## estimate variance of contrasts
