Tīmeklis2024. gada 12. apr. · R 2 of OLS, Ridge, Lasso are 1, 0.85, − 0.06, respectively. R 2 of OLS, Ridge, Lasso using 5 -fold cross validation scheme are 0.85, 0.83, − 0.05, respectively. With these values, what and how can I compare the R 2 values of the above three models? Thank you for reading my question. regression machine … Tīmeklis9. Since R^2 = 1 - RSS/TSS, the only case where RSS/TSS > 1 happens when our model is even worse than the worst model assumed (which is the absolute mean model). here RSS = sum of squares of difference between actual values (yi) and predicted values (yi^) and TSS = sum of squares of difference between actual values …
