Norminv rand 均数 标准差
WebThe first parameter, µ, is the mean. The second parameter, σ, is the standard deviation. The standard normal distribution has zero mean and unit standard deviation. The normal inverse function is defined in terms of the normal cdf as. x = F − 1 ( p μ, σ) = { x: F ( x μ, σ) = p }, where. p = F ( x μ, σ) = 1 σ 2 π ∫ − ∞ x ... WebIt might be possible, but I've never tried it. You're looking for a truncated normal distribution. Which is certainly possible in Matlab and such, which means it could be done with Excel, but it may require a bit of legwork. I would use the usual NORMINV(rand(),mean,st_dev) and then filter out anything outside your min and max.

Web22 de dez. de 2024 · In Excel, if you want to generate a column with random numbers that are normally distributed, you can use the NORMINV () function like this. You can specify the probability (which is usually a random number drawn from uniform distribution), mean and standard deviation. While DAX has the NORM.INV () function, M does not.
