【摘要】 当单调函数的反函数不能显性表示时 ,连续型随机变量的分布密度曲线仍可通过参数方程的形式获得。将这种方法应用到用h分布模型的密度曲线拟合t(6 )分布的密度曲线上面 ,拟合效果良好。更多还原

【Abstract】 When a inverse function of monotone function can not show the explicit formula,the distribution density curve of continuous randon variable can be gained with a parametric equation. And when this method applies to fitting density curve of t(6) with density curve of h-distibution model,the fitting effect is good.更多还原
