TG {BAS} | R Documentation |
Creates an object representing the Truncated Gamma (tCCH) mixture of g-priors on coefficients for BAS, where u = 1/(1+g) has a Gamma distribution supported on (0, 1].
TG(alpha = 2)
alpha |
a scalar > 0, recommended alpha=.5 (betaprime) or 1. alpha=2 corresponds to the uniform prior on the shrinkage factor. |
Creates a structure used for bas.glm
.
returns an object of class "prior", with the family and hyerparameters.
