summary.phylog.lm: Summarize a phylog.lm object

In PHYLOGR: Functions for Phylogenetically Based Statistical Analyses

Description

A 'method' for objects of class phylog.lm. Summarizes the results of the fitted linear models for the simulated (and original) data and returns p-values. There is a print 'method' for this summary.

Usage

## S3 method for class 'phylog.lm'
summary(object, ...)

Arguments

object	an object of class phylog.lm returned from a previous call to lm.phylog.
...	further arguments passed to or from other methods (currently not used).

Details

The p-value is computed as the (number of simulated data sets with F-value larger than original (”real”) data + 1) / (number of simulated data sets + 1). The quantiles are obtained with the function quantile, and thus linear interpolation is used.

Value

A list (of class summary.phylog.lm) with components

call	the call to lm.phylog
original.model	the model fitted to the original data.
original.Fvalue	the F-values from the original data.
p.value	the p-values for the marginal F-tests and overall F.
quant.F.value	the quantiles of the distribution of F-values from the simulated data.
num.simul	the number of simulations used in the analyses
