Hi,
    We are using the ij Curvefitrter class and using it for fitting curve using linear and power options. While linear fitting gives back the slope and intercept values same as when we add trendline to same set of data in Excel and get equation nfrom excel for slope and intercept, in case of power fitting, the values are different than the ones coming from trendline equation generated in Excel for same set of data.

Is this a known issue in CurveFitter or Excel? I need an answer quickly for this,kindly help.

Thanks,
Sharad
