使用sympy.stats.GammaInverse需要先导入sympy和sympy.stats: importsympyimportsympy.stats 创建一个Gamma逆分布的实例: a,b,x=sympy.symbols('a b x')y=sympy.stats.GammaInverse('y',a,b) 这里,a和b是分布的参数,y是随机变量的名称。 Gamma逆分布有几个常用的特殊情况,可以调用相应的函数来创建实例。例如...

work with Python 2.7, but Python 2 support will be removed soon.)NumPyandSciPyare also required, andMatplotlibis required to run the examples. If you don't already have Python, we recommend an "all in one" Python package such as theAnaconda Python Distribution, which is available for free...
