Description

A class for defining half cauchy priors to be translated to Stan code. Objects of class PriorHalfCauchy should not be created directly but by the constructor prior_half_cauchy().

Slots

stan_code

character. Stan implementation of the prior, with placeholders for the half cauchy stan function parameters surrounded with ⁠{{⁠ and ⁠}}⁠ to be replaced with glue::glue().

n_param

integer. Number of prior parameters (2).

constraint

character. Support of prior distribution. In a half cauchy prior, constraint is mu

mu

numeric. Location.

sigma
