The graphical pattern of a gaussian distribution always appears as a bell curve. Gaussian Distribution in Python Gaussian distribution in python is implemented using normal() function. The normal() function is included in the random module. It takes in the “size” of the distribution which we...
首先定义正态分布函数: defnormal_distribution(x,mu,sigma,A):returnA*np.exp(-0.5*((x-mu)/sigma)**2) 1. 2. 然后使用curve_fit函数进行拟合: fromscipy.optimizeimportcurve_fit params,covariance=curve_fit(normal_distribution,x,y,p0=[5,2,3])mu,sigma,A=params 1. 2. 3. 4. 3. 绘制拟合...
fig2, ax2 = plt.subplots() ax2.plot(N, probability(N),"k", label="True distribution") ax2.set_xlabel("Number of arrivals in 1 time unit") ax2.set_ylabel("Probability") ax2.set_title("Probability distribution") 现在,我们继续从我们的样本数据中估计速率。我们通过计算到达时间间隔的均值...
