WebOct 10, 2024 · Several ML approaches were trained including linear regression, regression trees, Gaussian process regression, the ensemble of trees, and SVR. Among those, the fine Gaussian SVR accurately exhibited the best fit model. Many evaluation metrics of the model prediction performance were computed including MSE, RMSE, and R 2 metrics. The latter ...

WebFeb 21, 2024 · A typical and straightforward power analysis for regressions (e.g., pwr.f2.test in the R pwr package [ 34 ]) applies only to the linear model–before finding which shape best represents the data. In principle, a power test is possible for a hump-shaped model [ 35 ], but conventional statistical power tests do not include that possibility.
