Dear Community,
rt ? D(?) and its a GED. Density is given as:
$fGED (x; \mu, \sigma, \nu) =$ $\frac{1} {2\sigma \nu ^{1/\nu }2 \Gamma \left(\frac{1}{\nu }+1\right)}$ $e^{(-\frac{1}{\nu}\frac{ | x-\mu |^\nu }{\sigma ^{\nu} })}$
Given that $\mu = 0$
They gave me the Tip that: $\frac{ \Gamma (\frac{a+1} c) } {{cb^{ \frac{a+1}{c} }}}$ $=\int_0^{\infty } x^a e^{-\text{bx}^c} \, dx$
Is their a way to calculate the first 4 Moments in Mathematica? I didn't find a Method in the Forum or in Google :)
Cheers
