The higher the r2, the better the model explains and predicts the outcomes If r2 is 0%, it means the model doesn't explain anything, and if it's 100%, it means the model explains everything. It's tempting to ask, what's a good r 2 r2 value? unfortunately, there's no single answer The definition of a good r 2 r2 depends heavily on the domain and the specific problem you're trying to solve R2 values (e.g., > 0.95) The underlying relationships are often precise.
Integrating statistical rigor and clinical judgment helps derive meaningful insights from clinical data This paper highlights key considerations for evaluating a “good” r 2 value in clinical medicine and concludes that an r 2 of >15% is a generally a meaningful value in clinical research.
