RE: Logarithmic Regression: Different correlation from 3 different calculators
I wonder if your r and r^2 values change slightly if you run the regression on normalized X, Y data?
Also, I think that calculating r for non linear regressions may require separate calculations of SSE and SST, then using r = sqrt(1 - SSE/SST) . |
