Dear Adrian and Ian (and r-helpers),
I encountered a curious result in developing an example using the bicreg
function in the BMA package: I noticed that pairs of models with equal R^2
and equal numbers of predictors had nevertheless different BIC values.
Looking at the bicreg function, the
Dear Adrian and Ian (and r-helpers),
To answer my own question: The difference is simply due to rounding; that
is, there are actually small differences in the R^2 values that account for
the differences in the BICs.
Sorry for the false alarm,
John
