Dear Community Members,
When I use curve fitter for equation in the form f(x,y)=a*x^n/(y+b)^m, the results are very bad (R-square is very, very low).
After removing "b" or changing it with a random number (for example 8, then f(x,y)=a*x^n/(y+8)^m), R-square is very good.
The question is: Is this a limitation of the software or there is a way to overcome this problem and to use "b", which value wiil be calculated by Curve fitter.Dear Community Members,
