Need Help Finding The First 4 PWM of the generalized normal distribution
f(x)= $\displaystyle
\frac{1}{\alpha\sqrt{2\pi}}e^{ky-\frac{y^2}{2}}
$
where
$\displaystyle
y= -k^{-1}log(1-k(x-\epsilon)/\alpha)
$
$\displaystyle
\epsilon+\frac{\alpha}{k}<x< \infty
$
F(x)= $\displaystyle
\int^{y}_{-\infty} e^{\frac{-t^2}{2}}~dt
$
