Bernoulli {BAS} | R Documentation |
Creates an object representing the prior distribution on models for BAS.
Bernoulli(probs=.5)
probs |
a scalar or vector of prior inclusion probabilities. If a scalar, the values is replicated for all variables ans a 1 is added for the intercept. BAS checs to see if the length is equal to the dimension of the parameter vector for the full model and addas a 1 to include the intercept. |
The independent Bernoulli prior distribution is a commonly used prior in BMA, with the Uniform distribution a special case with probs=.5. If all indicator variables have a independent Bernoulli distributions with common probability probs, the distribution on model size binomial(p, probs) distribution.
returns an object of class "prior", with the family and hyerparameters.
