This distribution arises in the stochastic frontier model because it is the distribution of the composed error, which is the sum (or difference) of a Normal and a Half-Normal random variable. The cdf must be evaluated in models in which the composed error is linked to other errors using a...

This calculator will compute the cumulative distribution function (CDF) for the normal distribution (i.e., the area under the normal distribution from negative infinity to x), given the upper limit of integration x, the mean, and the standard deviation. ...
legend('CDF of sample', 'CDF of normal distribution') hold off ``` 在这段代码中,我们使用 cdf 函数来计算正态分布函数的值,并从第三个输入参数开始传递均值和标准差的值。我们可以将样本数据和概率分布函数作为两个不同的曲线可视化,将其放在同一个图表上,这样我们可以更好地比较两个分布的形状和位置。

p = normcdf(x) returns the cumulative distribution function (cdf) of the standard normal distribution, evaluated at the values in x. example p = normcdf(x,mu) returns the cdf of the normal distribution with mean mu and unit standard deviation, evaluated at the values in x. p = normcdf...
