Likelihood ratio test — blr_test_lr • blorr

Performs the likelihood ratio test for full and reduced model.

Usage

blr_test_lr(full_model, reduced_model)

# Default S3 method
blr_test_lr(full_model, reduced_model)

Arguments

full_model: An object of class glm; model with all predictors.
reduced_model: An object of class glm; nested model. Optional if you are comparing the full_model with an intercept only model.

Value

Two tibbles with model information and test results.

model_1 <- glm(honcomp ~ female + read + science, data = hsb2,
            family = binomial(link = 'logit'))

blr_test_lr(model_1)

# compare full model with nested model
# nested model
