Usage
.beta_parm(b, to = "alpha.beta")
Arguments
- b
vector A named vector specifying non-NULL values for 2
parameters. e.g. c(alpha = NA, beta = NA, mu = .6, theta = NA, phi = 1.6,
sigma2 = NA) or just c(mu = .6, phi = 1.6)
- to
Specification of desired parameters, options are one of
"alpha.beta", "mu.phi", "mu.theta" or "mu.sigma2".
Value
vector A named vector with values for the parameters specified in
the "to" argument of the input.
