cdfis a generic function that accepts either a distribution by its namenameor a probability distribution objectpd. It is faster to use a distribution-specific function, such asnormcdffor the normal distribution andbinocdffor the binomial distribution. For a list of distribution-specific functions, s...

高斯分布(Gaussian distribution):又名正态分布(Normal distribution),也称“常态分布” 一维正态分布函数: 卡尔曼滤波(Kalman filtering):一种利用线性系统状态方程,通过系统输入输出观测数据,对系统状态进行最优估计的算法。 X(k)=A X(k-1)+B U(k)+W(k) 极大似然估计方法(Maximum Likelihood Estimate,MLE):...
Normal Distribution cdf Compute the cdf values evaluated at the values inxfor the normal distribution with meanmuand standard deviationsigma. x = [-2,-1,0,1,2]; mu = 2; sigma = 1; p = normcdf(x,mu,sigma) p =1×50.0000 0.0013 0.0228 0.1587 0.5000 ...
这里Python scipy 用了 ppf, 'One-tail test' on the normal distribution density plot 相当于一种特殊的 pdf 函数。 ## 先求标准正太分布的临界值 import scipy.stats z_cv = -scipy.stats.norm.ppf((1 - 90/100)) # z critical value z_cv 已知临界值,那么我们就可以求出具体的对应分数: from mat...
