hetprior: Informative bayesian prior lookup for heterogenity in...

In mcguinlu/hetprior: What the Package Does (One Line, Title Case)

Description

hetprior returns an informative Bayesian prior based on the conditions specified

Usage

hetprior(priorid, statistic, details)

Arguments

priorid	Prior ID number.
statistic	Descriptive statistic required. Options allowed are "mean" or "sd" for lognormal, log(t), and logit(t) distributions, and "shape" or "scale" for inverse gamma distributions.
details	Outputs information on the selected prior. Default = FALSE.

Details

This function uses data from five original studies to provide a repository of informative priors for the heterogeneity observed in meta-analysis of studies in particular areas of health care.

Value

hetprior returns the specific descriptive statistic for a specified informative prior distribtution for the conditions
