Re: Wrong correlation coefficient

sorry it's mathematical error now I do double[] tab_temp_poly = new double[polyFitting1.PolyDegree]; tab_temp_poly[5] = polyFitting1.Coefficient(5); tab_temp_poly[4] = polyFitting1.Coefficient(4) - 5 * polyFitting1.Coefficient(5) * xmin; tab_temp_poly[3] = polyFitting1.Coefficient(3) + 10 * polyFitt...

Re: Wrong correlation coefficient

I use teechartnet2010. I need to use the polynomial coefficient with a polynomial degree 6. I understand that your coefficient is for normalised value. I draw a series point1. I Apply polyfitting function on this curve. every things is OK. I change polynomial coefficient by : double[] tab_temp_poly ...
