一种适用于拟合单峰分布数据的模型

A Model for Single Peak Distribution Data

针对一类二参数概率模型 ,选取特殊的参数值 ,做出一批有代表性的概率密度曲线 ,并通过这些密度曲线揭示出模型中各参数的统计含义及模型所适用的拟合数据的范围 .通过一个实例 ,给出了利用这类模型拟合单峰分布数据的方法步骤和拟合效果 。

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.
