priorOnAlpha_spec: Specify prior on alpha.

In telescope: Bayesian Mixtures with an Unknown Number of Components

Specify prior on \alpha.

Description

Obtain a function to evaluate the log prior specified for \alpha.

Usage

priorOnAlpha_spec(H = c("alpha_const", "gam_05_05", "gam_1_2", "F_6_3"))

Arguments

H	A character indicating which specification should be used.

Details

The following prior specifications are supported:

• "alpha_const": \alpha is fixed at 1.

• "gam_05_05": \alpha \sim gamma(0.5, 0.5), i.e., shape = 0.5, rate = 0.5.

• "gam_1_2": \alpha \sim gamma(1, 2), i.e., shape = 1, rate = 2.

• "F_6_3": \alpha \sim F(6, 3), i.e., an F-distribution with degrees of freedom equal to 6 and 3.

Value

A named list containing:

• "log_pAlpha": a function of the log prior of \alpha.

• "param": a list with the parameters.
