GetAICWeights: Compute model weights

In thej022214/hisse: Hidden State Speciation and Extinction

Compute model weights

Description

Computes the Akaike model weights for a list of HiSSE, MiSSE, and/or GeoHiSSE model fits.

Usage

GetAICWeights(hisse.results, criterion="AIC")

Arguments

hisse.results	A list of models (such as from MiSSEGreedy or just putting individual hisse runs in a list)
criterion	Which criterion to use, AIC or AICc (with correction for sample size)

Details

Function computes the model weight from their AIC values using the formula:

“delta <- mod.AIC - min( mod.AIC )”

“AICw <- exp( -0.5 * delta) / sum( exp( -0.5 * delta) )”

Function will return vector of weights
