Details
Posterior model odds are calculated for every model i
as
\mathrm{pMO}_i = \frac{\mathrm{exp}\Big[-\frac{1}{2}\Delta_i\mathrm{BIC}\Big]}{\sum_{j = 1}^K\mathrm{exp}\Big[-\frac{1}{2}\Delta_j\mathrm{BIC}\Big]},
where the minimal BIC value is subtracted from all BICs. In other words: the model with the lowest BIC has \Delta\mathrm{BIC}=0
.
Value
posteriorModelOdds
returns to posterior model odds for the models provided.

lm.2 <- lm(mpg ~ hp * wt, data = mtcars)
lm.3 <- lm(mpg ~ hp * wt + gear, data = mtcars)
posteriorModelOdds(lm.1, lm.2, lm.3)
