"WebThis research also highlights the noticeable contribution of the inclination in the accuracy of the model with respect to the others, which is 16.4 times higher than that of the less relevant one (height of flight). This leads to propose avoiding inclination angle as a variable, and the sole development of nadiral flights to obtain accurate models. " - Metric and non-metric variables in research

Web19 mei 2024 · 5) R Squared (R2) R2 score is a metric that tells the performance of your model, not the loss in an absolute sense that how many wells did your model perform. In contrast, MAE and MSE depend on the context as we have seen whereas the R2 score is independent of context. WebThis technique is considered appropriate when several metric dependent variables are involved in a research study along with many non-metric explanatory variables. (But if the study has only one metric dependent variable and several nonmetric explanatory variables, then we use the ANOVA technique as explained earlier in the book.)
