Polynomial regression for prediction
WebOct 30, 2014 · It is not clear from your description what sort of polynomial regression you would use. It is possible that the (linear) correlation between x and y is say .2, while the linear correlation between x^2 and y is .9. Thus, the polynomial regression y = b*x^2+a might yield a better model (e.g. for predictions) then the linear regression model y = b ...

WebJul 30, 2024 · This is equivalent to y = mx + c. By polynomial transformation, what we are doing is adding another variable from a higher degree. For instance, the above equation can be transformed to, y=a2x2 + a1x + a0. by adding a a 2 x 2 term. The model we develop based on this form of the equation is polynomial in nature. WebMar 14, 2024 · We also fit the SVR models using the linear, polynomial, radial, and sigmoid kernel functions. The best method is selected by based on the prediction evaluation metrics discussed in section Key performance indicators. The predictions from the GAM, GBM, and SVR models are combined using the LQRA approach.

In our earlier discussions on multiple linear regression, we have outlined ways to check assumptions of linearity by looking for curvature in various plots. For instance, we look at the scatterplot of the residuals versus the fitted values. We also look at a scatterplot of the residuals versus each predictor.
