intrinsic {BAS} | R Documentation |
Creates an object representing the intrinsic prior on g, a special case of the tCCH mixture of g-priors on coefficients for BAS.
intrinsic(n = NULL)
n |
the sample size; if NULL, the value derived from the data in the call to 'bas.glm' will be used. |
Creates a structure used for bas.glm
.
returns an object of class "prior", with the family "intrinsic" of class "TCCH" and hyperparameters alpha = 1, beta = 1, s = 0, r = 1, n = n for the tCCH prior where theta in the tCCH prior is determined by the model size and sample size.
