NettetThe meaning of r 2. The value r 2 is a fraction between 0.0 and 1.0, and has no units. An r 2 value of 0.0 means that knowing X does not help you predict Y.

That would be very helpful if I wanted to find the best fit of a linear model. Sadly, I want the best fit in general; and it looks like the best fit contains a division (e.g. a/X + b * X where a * b would need to be estimated). Hey - this gives me an idea - maybe I can use OLS and provide 1/X as one of the predictors. NettetThe definition of R-squared is fairly straight-forward; it is the percentage of the response variable variation that is explained by a linear model. Or: R-squared = Explained variation / Total variation. R-squared is always between 0 and 100%: 0% indicates that the model explains none of the variability of the response data around its mean. citadel m1 9mm carbine wood stock 10 rd
