RMSE is a popular formula to measure the error rate of a regression model. Unlike RMSE, the relative squared error (RSE) can be compared between models. The coefficient of determination (R2) summarizes the explanatory power of the.
The root-mean-square deviation (RMSD) or root-mean-square error (RMSE) is a frequently used measure of the differences between values (sample and population values.

There’s some line that minimizes the square. it’s also called R-squared. You might have even heard that term when people talk about regression. Now let’s think about it. If the squared error of the line is really small what does that.
