prior_odds 
Optional vector of prior odds for the models. See

Inclusion Bayes factors answer the question: Are the observed data more probable under models with a particular effect, than they are under models without that particular effect? In other words, on average  are models with effect X more likely to have produced the observed data than models without effect X?
If match_models=FALSE
(default), Inclusion BFs are computed by comparing
all models with a term against all models without that term. If TRUE
,
comparison is restricted to models that (1) do not include any interactions
with the term of interest; (2) for interaction terms, averaging is done only
across models that containe the main effect terms from which the interaction
term is comprised.
a data frame containing the prior and posterior probabilities, and log(BF) for each effect.
A Bayes factor greater than 1 can be interpreted as evidence against the null, at which one convention is that a Bayes factor greater than 3 can be considered as "substantial" evidence against the null (and vice versa, a Bayes factor smaller than 1/3 indicates substantial evidence in favor of the nullmodel) (Wetzels et al. 2011).
Random effects in the lmer
style are converted to interaction terms:
i.e., (XG)
will become the terms 1:G
and X:G
.
