prepare_stan_data_equidistant: Prepare data for equidistant threshold Stan model

In clmstan: Cumulative Link Models with 'CmdStanR'

Prepare data for equidistant threshold Stan model

Description

Creates a Stan data list for cumulative link models with equidistant (equally spaced) thresholds: c_k = c_1 + (k-1) * d

Usage

prepare_stan_data_equidistant(
  formula,
  data,
  link = "logit",
  link_param = NULL,
  prior_beta_sd = 2.5,
  prior_c1_mu = 0,
  prior_c1_sd = 10,
  prior_d_alpha = 2,
  prior_d_beta = 0.5
)

Arguments

formula	A formula specifying the model
data	A data frame containing the variables
link	Link function name
link_param	A list of link parameters (for flexible links)
prior_beta_sd	Prior SD for regression coefficients (default: 2.5)
prior_c1_mu	Prior mean for first threshold c1 (default: 0)
prior_c1_sd	Prior SD for first threshold c1 (default: 10)
prior_d_alpha	Gamma prior shape for interval d (default: 2)
prior_d_beta	Gamma prior rate for interval d (default: 0.5)

Value

A list suitable for passing to CmdStan (clm_equidistant.stan)
