Extract Beta Parameters from Model Output

This function extracts beta coefficients from a model parameter object, separating them into beta1 and beta2 components.

Usage

extract_betas(
  params_result,
  params = c("gamma", "log_sigma2", "log_phi", "log_tau1")
)

Arguments

params_result

A model parameter object containing parameter estimates

params

A character vector specifying parameter names, defaults to c("gamma", "log_sigma2", "log_phi", "log_tau1")

Value

A list with two components:

• beta1: First set of beta coefficients

• beta2: Second set of beta coefficients

Details

The function assumes the parameter vector contains beta coefficients followed by other model parameters. It splits the betas into two equal groups after removing the last 4 parameters.
