sd_to_prec: Transform a prior from SD to precision.
In mcp: Regression with Multiple Change Points
sd_to_prec R Documentation
Transform a prior from SD to precision.
Description
JAGS uses precision rather than SD. This function converts
dnorm(4.2, 1.3) into dnorm(4.2, 1/1.3^2). It allows users to specify
priors using SD and then it's transformed for the JAGS code. It works for the
following distributions: dnorm|dt|dcauchy|ddexp|dlogis|dlnorm. In all of
these,
tau/sd is the second parameter.
Usage
sd_to_prec(prior_str)
Arguments
prior_str
String. A JAGS prior. Can be truncated, e.g.
dt(3, 2, 1) T(my_var, ).
Value
A string
