ordered_response_log_probability: Construct a native ordered-response log-likelihood expression

In rbiogeme: Interface to 'Biogeme'

Construct a native ordered-response log-likelihood expression

Description

The observed response is matched to categories; the intervals are defined by the ordered cutpoints. This internal helper selects the native logistic or normal cumulative distribution. No probability is evaluated in R.

Usage

ordered_response_log_probability(
  distribution = c("logit", "probit"),
  eta,
  cutpoints,
  alternative,
  categories = NULL,
  neutral_labels = numeric(),
  enforce_order = TRUE,
  eps = 1e-12
)

Arguments

distribution	Native ordered-response distribution.
eta	Latent-index expression.
cutpoints	Non-empty list of cutpoint expressions.
alternative	Observed response expression.
categories	Optional ordered numeric labels. If omitted, native Biogeme uses 0:(length(cutpoints)).
neutral_labels	Optional numeric labels whose contribution is one.
enforce_order	Whether native Biogeme should enforce ordered cutpoints during evaluation.
eps	Positive numerical lower bound used by native Biogeme.

Value

A Biogeme expression compiled to native Biogeme.
