Show that you can use the Laplace Transforms to generate moments a random variable: xn = E[X^n] for any { n, integer >0 } Laplace Transform: fx(x) f(s)=infiinity integrate0 fx(x)e-sx dx=E[e^-sx Moment Generator: E[x^n]=(-1)^n dn/ds^n f *(s), {evaluate at s=0} use the Taylor Series of the exponential function: ex = infinity sigma n=01/nx^ninterchange the integration operation with the summation operation.
