在MATLAB 中,处理标准正态分布(均值为 0,标准差为 1 的正态分布)的函数主要包括 normpdf、normcdf 和norminv 等。这些函数分别用于计算标准正态分布的概率密度函数 (PDF)、累积分布函数 (CDF) 以及逆累积分布函数 (Inverse CDF)。以下是对这些函数的详细介绍和示例代码。 1. 概率密度函数 (PDF
Find the inverse cdf value at 0.5 and its 99% confidence interval. [x,xLo,xUp] = norminv(0.5,muHat,sigmaHat,pCov,0.01) x = 4.9347 xLo = 4.7721 xUp = 5.0974 xis the inverse cdf value using the normal distribution with the parametersmuHatandsigmaHat. The interval[xLo,xUp]is the 99%...
functionz=standard_normal_inverse() u1=rand(); u2=rand(); z1=sqrt(-2*log(u1))*cos(2*pi*u2); z2=sqrt(-2*log(u1))*sin(2*pi*u2); z=[z1,z2]; end 步骤二:计算正态分布反函数 在得到标准正态分布的反函数之后,我们可以使用线性变换将其转换为任意均值和方差的正态分布。 2.1 正态分...
