CCH {BAS} | R Documentation |
Creates an object representing the CCH mixture of g-priors on coefficients for BAS .
CCH(alpha, beta, s = 0)
alpha |
a scalar > 0, recommended alpha=.5 (betaprime) or 1 for CCH. The hyper.g(alpha) is equivalent to CCH(alpha -2, 2, 0). Liang et al recommended values in the range 2 < alpha_h <= 4 |
beta |
a scalar > 0. The value is not updated by the data; beta should be a function of n for consistency under the null model. The hyper-g corresponds to b = 2 |
s |
a scalar, recommended s=0 |
Creates a structure used for bas.glm
.
returns an object of class "prior", with the family and hyperparameters.
