beta.draws.bma {BMS} | R Documentation |
Returns a matrix whose columns are the (expected value or standard deviations of) coefficients for the best models in a bma object.
beta.draws.bma(bmao, stdev = FALSE)

a 'bma' object (as e.g. resulting from |
stdev |
if |
Each column presents the coefficients for the model indicated by its
column name. The zero coefficients are the excluded covariates per model.
Note that the coefficients returned are only those of the best (100) models
encountered by the bma
object (cf. argument nmodels
of
bms
).
For aggregate coefficients please refer to coef.bma
.
Note that the elements of beta.draws.bma(bmao)
correspond to
bmao$topmod$betas()
