Creates an object representing the hyper-g mixture of g-priors on
coefficients for BAS.
Arguments
- alpha
a scalar > 0. The hyper.g(alpha) is equivalent to CCH(alpha -2,
2, 0). Liang et al recommended values in the range 2 < alpha_h <= 3
Value
returns an object of class "prior", with the family and
hyerparameters.
Details
Creates a structure used for bas.glm.
