normal distribution 通过使用np.random.normal从相同mean值,但是不同标准差的正态分布中采样100000个数据,随后将这些数据的直方图画出来,就可以近似作为正态分布的密度函数PDF了. #Draw 100000 samples from Normal distribution with stds of interest: samples_std1, samples_std3, samples_std10samples_std1 = np...
Note: A normal distribution graph is also known as the bell curve because of it's characteristic shape of a bell.Histogram ExplainedWe use the array from the numpy.random.normal() method, with 100000 values, to draw a histogram with 100 bars....

Python numpy.random.normal() MethodThe numpy.random.normal() draw random samples from a normal (Gaussian) distribution. It takes some parameters like loc, scale, and size. Loc is the center of the distribution. Scale is the standard deviation of the distribution and size is the output shape...
