In the general … Tīmeklis2024. gada 10. janv. · R 2 indicates the proportion of data points which lie within the line created by the regression equation. A higher value of R 2 is desirable as it indicates better results.

TīmeklisIf the regressors do not include a constant but (as some regression software packages do) you nevertheless calculate R 2 by the formula. R 2 = 1 − ∑ i = 1 n e i 2 ∑ i = 1 n ( y i − y ¯) 2. then the R 2 can be negative. This is because, without the benefit of an intercept, the regression could do worse than the sample mean in terms of ...
