In reportRmd: Tidy Presentation of Clinical Reporting
GVIF R Documentation
Compute Generalized Variance Inflation Factor (GVIF)
Description
Calculates GVIF for model terms to detect multicollinearity.
Adapted from the car package.
Usage
GVIF(model)
Arguments
model
Fitted model object (lm, glm, coxph, etc.)
Details
For terms with degrees of freedom > 1 (e.g., factor variables),
returns GVIF^(1/(2*df)) for comparability with standard VIF.
Value
Data frame with columns: Covariate (term name) and VIF (value)
