【Abstract】 For a sort of two parameter probability models with their parameters specifically chosen, a class of typical probability density curves is drawn out. On the basis of the curves, statistical meaning of parameters in the model and the data range of fitting are revealed. Through an example, the steps of fitting single peak distribution data are listed. Finally, a generalized model is used to obtain a better precision of fitness.更多还原
