anova.sjSDM {sjSDM}

Anova

Description

Calculates type II anova.

Shared contributions (e.g. between space and environment) are also calculated (and divided proportionally) and can be optionally visualized via plot.sjSDManova with add_shared=TRUE. The anova can get unstable for many species and few occurrences/observations. We recommend using large numbers for 'samples'.

Usage

## S3 method for class 'sjSDM'
anova(object, samples = 5000L, ...)

Arguments

object

model of object sjSDM

samples

Number of Monte Carlo samples

...

optional arguments which are passed to the calculation of the logLikelihood

Details

Compute analysis of variance

Value

An S3 class of type 'sjSDManova' including the following components:

results

Data frame of results.

to_print

Data frame, summarized results for type I anova.

N

Number of observations (sites).

spatial

Logical, spatial model or not.

species

individual species R2s.

sites
