Thecoefficient of determination(R-squared) is a statistical metric that is used to measure how much of the variation in outcome can be explained by the variation in the independent variables. R2always increases as more predictors are added to the MLR model, even though the predictors may not ...
In addition, the distributions of sample squared multiple correlations and sample squared cross-validity coefficients are affected by categorization mainly through the attenuations of R 2 P and R2 cv . Consequently, the formula estimators of R2 p and R2 cv were found to be as accurate and ...

R square is the squared (Pearson) correlation betweenpredicted and actual values. We're interested in R square because it indicates how well our model is able to predict a variable of interest. An R square value of 0.65 like we found is generally considered very high; our model does a ...

To test the quality of function f, we evaluate the mean-squared error (MSE) on the last point of every time series on that target gene. The Random Forest uses bootstrap aggregation, where each new tree is trained on a sub-sample of the training data points. The Out-of-Bag error for...
