WebThe Rayleigh distribution, named for William Strutt, Lord Rayleigh, is the distribution of the magnitude of a two-dimensional random vector whose coordinates are independent, identically distributed, mean 0 normal variables. The distribution has a number of applications in settings where magnitudes of normal variables are important. WebRayleigh distribution is a continuous probability distribution for positive-valued random variables. The data can be given by the mean value and a lower bound, or by a parameter θ and a lower bound. These are interconnected by a well-documented relationship given in the literature. For instance, if the mean μ=2 and the lower bound is γ=0.5, then θ=1.59577 and … WebRayleigh Distribution. Rayleigh distribution is used in signal processing.

"WebA random vibration is one whose absolute value is not predictable at any point in time. As opposed to sinusoidal vibration, there is no well defined periodicity - the amplitude at any point in time is not related to that at any other point in time. Figure 2 shows the amplitude time history of a random vibration. " - Rayleigh distribution random vibration
