Cumulants are essentially defined as the coefficients of the Taylor expansion of the logarithm of the Fourier transform of the density function about the zero frequency
WHAT??!!

I thought they were a sort of cloud… :-/
oic
much better! :)
i like that they are “essentially” defined thus.
also, is it worrying that it makes some sense to me? the “fourier transform… about the zero frequency” is a bit funny though as, i think, is just a fancy pants way of saying, integrate from -infinity to +infinity, which is always 1 for a probability density.
that would make it taylor expansion of zero, thus cumulants don’t exist
actually that makes it much easier, blodgett will just cross out these sections of tutorial
yarr, everyone knows maths is just cancelling stuff out until you have nothing left. that’s how you know you got the right answer.
