Thanks, I meant finite dimension for X.

comment Normal distribution of x, xdot
With the histogram I presented I have 120 seconds sampled using 20K samples/sec, but I have much more data.

comment Normal distribution of x, xdot
This is a biological measurements from cells, and x is the voltage which fluctuate quite randomly, due to external (non-measured) events. No observable oscillations there!

comment Normal distribution of x, xdot
Ok, this is experimental measurements so obviously I don't have access to xdot, just to (x(t+dt)-x(t))/dt for dt of my choise (sampling frequency). I believe the variance of x is fixed as t increases, which is inconsistent with a Wiener process. I'll recheck this.

comment Normal distribution of x, xdot
The case here is of a complex dynamic system which is indeed bounded, so your comment is very interesting. Can you suggest some intuition why do such relation occur (relation by Fourier transform)?
