Webdistribution for its instantaneous values will tend to follow a Normal distribution, which is the same distribution corresponding to a broadband random signal. The absolute values of the system’s response peaks, however, will have a Rayleigh distribution. Derivation From Reference 1, the probability density function n A; , Webrayleigh is a special case of chi with df=2. The probability density above is defined in the “standardized” form. To shift and/or scale the distribution use the loc and scale parameters. Specifically, rayleigh.pdf (x, loc, scale) is identically equivalent to rayleigh.pdf (y) / scale with y = (x - loc) / scale. Note that shifting the ... how offset accounts work
