get_Akaike_weights_from_rel_likes_pairwise: Calculate the Akaike Weights, from the relative likelihoods of the models

Description

Given the relative likelihoods of the models, calculate the Akaike weight of the models. Akaike weights sum to 1.

Usage

get_Akaike_weights_from_rel_likes_pairwise(rel_likes_AIC_pairwise)

Arguments

rel_likes_AIC_pairwise

A 2-column data.frame of relative likelihoods of each pair of models.

Value

Akaike_weights_pairwise A data.frame of Akaike Weights for each row (column 1) and the reference model (column 2). Note that only 2 models are being compared in each row, not all of them, as in get_Akaike_weights_from_rel_likes.

Details

See Burnham et al. (2002) and http://www.brianomeara.info/tutorials/aic for discussion of AIC and its uses.
