Sigma statistics meaning
WebThe K-S statistic reported is alpha, where alpha is the reject level for the hypothesis that the fitted curve is the same as the empirical curve. K-S should be a high value (Max =1.0) when the fit is good and a low value (Min = 0.0) when the fit is not good. When the K-S value goes below 0.05, you will be informed that the Lack of fit is ... http://brownmath.com/swt/symbol.htm
