std::lognormal_distribution

The lognormal_distribution random number distribution produces random numbers x > 0 according to a Log-normal distribution:

\({\small f(x;m,s) = \frac{1}{sx\sqrt{2\pi} } \exp{(-\frac{ {(\ln{x} - m)}^{2} }{2{s}^{2} })} }\)f(x; m,s) =

1

sx√2 π

exp⎛
⎜
⎝-

(ln x - m)2

2s2

⎞
⎟
⎠

The parameters m and s are, respectively, the mean and standard deviation of the natural logarithm of x.

std::lognormal_distribution satisfies all requirements of RandomNumberDistribution.
