priorp2g {mombf}

Moment and inverse moment prior elicitation

Description

priorp2g finds the g value giving priorp prior probability to the interval (-q,q).

Usage

priorp2g(priorp, q, nu=1, prior=c("iMom", "normalMom", "tMom"))

Arguments

prior

prior=='normalMom' does computations for the normal moment prior, prior=='tMom' for the T moment prior, prior=='iMom' does computations for the inverse moment prior. Currently prior=='tMom' is not implemented in priorp2g.

q

priorp2g returns g giving priorp prior probability to the interval (-q,q).

nu

Prior degrees of freedom for the T moment prior or the iMom prior (ignored if prior=='normalMom').

priorp

priorp2g returns g giving priorp prior probability to the interval (-q,q)

Details

See pmom and pimom for the MOM/iMOM cumulative distribution functions.

Value

priorp2g returns g giving priorp prior probability to the interval (-q,q).
