sim_rstar_glm: Simulate Data and Fit GLM and r* Models

Description

This function generates simulated data for main and control groups, fits a generalized linear model (GLM) and an r* model, and returns the results.

Usage

sim_rstar_glm(
  n_main,
  n_covariates,
  true_coef_main,
  n_control = NULL,
  true_coef_control = NULL,
  treatment_effect = NULL,
  model = c("logistic", "linear", "poisson"),
  skewness_main = NULL,
  skewness_control = NULL,
  Sigma_main = NULL,
  Sigma_control = NULL,
  ...
)

Value

A list with fitted GLM and r* models, and the simulated data.

Arguments

n_main

Number of observations in the main group.

n_covariates

Number of covariates.

true_coef_main

True coefficients for the main group.

n_control

Number of observations in the control group.

true_coef_control

True coefficients for the control group.

treatment_effect

Treatment effect size.

model

Type of model: "logistic", "linear", or "poisson".

skewness_main

Skewness for the main group covariates.

skewness_control

Skewness for the control group covariates.

Sigma_main

Covariance matrix for the main group covariates.

Sigma_control

Covariance matrix for the control group covariates.
