How to square all the values in a vector in R? Ask Question Asked 12 years, 2 months ago Modified 5 years, 8 months ago
- Function to calculate R2 (R-squared) in R - Stack Overflow
Warning R squared between two arbitrary vectors x and y (of the same length) is just a goodness measure of their linear relationship Think twice!! R squared between x + a and y + b are identical for any constant shift a and b So it is a weak or even useless measure on "goodness of prediction" Use MSE or RMSE instead: How to obtain RMSE out of lm result? R - Calculate Test MSE given a
