weight.IC: Get IC weights

In mmodely: Modeling Multivariate Origins Determinants - Evolutionary Lineages in Ecology

Get IC weights

Description

An implementation of IC weighting that first calulates the difference in IC values by subtracting all values from the lowest IC value. Second, the changes are expoentiated divided by a sum of the same and exponentiated yet again.

Usage

weight.IC(IC)

Arguments

IC	a vector of IC values

Value

a vector of IC based weights

Examples

data.path <- system.file("extdata","primate-example.data.csv", package="mmodely")
data <- read.csv(data.path, row.names=1)
pvs <- names(data[3:5])
data$gn_sp <- rownames(data)

tree.path <- system.file("extdata","primate-springer.2012.tre", package="mmodely")
phyl <- ape::read.tree(tree.path)[[5]]

comp <- comp.data(phylo=phyl, df=data)

mods <- get.model.combos(predictor.vars=pvs, outcome.var='OC', min.q=2)

PGLSi <- pgls.iter(models=mods, phylo=phyl, df=data, k=1,l=1,d=1) 

AICc.w <- weight.IC(IC=PGLSi$optim$AICc)
