Obtain a function to evaluate the log prior specified for \(\alpha\).
priorOnAlpha_spec(H = c("alpha_const", "gam_05_05", "gam_1_2", "F_6_3"))A named list containing:
"log_pAlpha": a function of the log prior of \(\alpha\).
"param": a list with the parameters.
A character indicating which specification should be used.
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.
