Polynomial regression for prediction
WebFeb 27, 2024 · Polynomial regression — intuition. Linear regression is very good and simple statistical method. However, sometimes data is spread too much and linear function is just not enough. Sometimes, we need some more complex function to make good prediction. This is where we could use polynomial regression. 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.
