Advanced Search WebAccordingly, Rayleigh and Kuiper tests clearly reject the hypothesis of uniformity at any level of significance. In other words, extreme storms are not randomly distributed around the circle (i.e., along the year) but concentrate during late autumn, winter, and early spring, with the more intense conditions observed during winter.

Webfor departure from uniformity is the Rayleigh test (introduced by Lord Rayleigh in1880, but also defined in the four monographs listed above). The test statistic for this test is derived from the ‘mean resultant length’ (r), which is a mea-sure of the concentration of data points around a circle. The test supports rejection of uniformity ... WebFeb 23, 2024 · A Rayleigh test, designed to detect unimodal von Mises (the circular analogue of the normal distribution) departure from uniformity, was conducted (Batschelet Reference Batschelet 1981); however, the Rayleigh test has very low potential to detect multimodal distributions.
