Normal(Gaussian) Distribution Function in C++

Question

I need to know a way to have the Gaussian Distribution of 50 numbers. I know of the Boost library, which generates random numbers. In my case, I don\'t need random numbers; I ne

Answer 1

If I got your question right you looking for the estimated normal distribution, that is for the sample mean and the variance of the sample .

The former is calculated as:

and the latter as:

The sample mean can be used as expected value and the sample variance as in the gaussian distribution:

I hope that answered your question ;)
