WebJun 15, 2024 · The red bar chart gives the standardized Rayleigh entropy contribution value corresponding to the eigenvalue. As a result, when using improved KECA for clustering analysis, the eigenvectors which contribute most to Rayleigh entropy, corresponding to the first, fourth and sixth components, will be used as projection vectors. The raw moments are given by: where is the gamma function. The mean of a Rayleigh random variable is thus : The standard deviation of a Rayleigh random variable is: The variance of a Rayleigh random variable is : WebDetails. The Rayleigh distribution arises as the distribution of the square root of an exponentially distributed (or χ 2 2 -distributed) random variable. If X follows an exponential distribution with rate λ and expectation 1 / λ, then Y = X follows a Rayleigh distribution with scale σ = 1 / 2 λ and expectation π / ( 4 λ). raymond santillanes homicide alb nm nov 2019
