WebSUMMARY An analogue of the Rayleigh test is developed for weighted vector data. It is sensitive to nonrandom concentration or scatter of vector angles, and can be used also to test certain group differences or interactions. The test is based upon rank transformation of vector weights and calculation of a resultant; it is nonparametric. Critical values of … WebThe Rayleigh distribution is a distribution of continuous probability density function. It is named after the English Lord Rayleigh.
