biogeme_beta: Create a Biogeme parameter

In rbiogeme: Interface to 'Biogeme'

Create a Biogeme parameter

Description

Create a Biogeme parameter

Usage

biogeme_beta(
  name,
  start = 0,
  lower = NULL,
  upper = NULL,
  fixed = FALSE,
  sigma_prior = 5,
  prior = NULL
)

Arguments

name	Parameter name.
start	Initial value.
lower	Optional lower bound.
upper	Optional upper bound.
fixed	Logical value indicating whether the parameter is fixed.
sigma_prior	Standard deviation of the native default normal prior.
prior	Optional declarative prior from biogeme_prior(). It is compiled into a native PyMC prior factory; R callbacks are not accepted.

Details

Parameter names are preserved exactly by the bridge and are therefore part of the equivalence contract with native Biogeme. Bounds and fixed are passed to the native parameter definition.

Value

A parameter expression.

Examples

b_cost <- biogeme_beta("b_cost", start = -1, upper = 0)
b_cost
