testBF.prior {BAS} | R Documentation |
Creates an object representing the prior distribution on coefficients for BAS that corresponds to the test-based Bayes Factors.
testBF.prior(g)
g |
a scalar used in the covariance of Zellner's g-prior, Cov(beta) = sigma^2 g (X'X)^- |
Creates a prior object structure used for BAS in 'bas.glm'.
returns an object of class "prior", with the family and hyerparameters.
