WebA Rayleigh test of the same distribution yields p=.033. This result illustrates that the Rao test is not the most porwerful in all cases. In particular, it is less powerful than alternative tests when the distribution is unimodal or multi-modal on a global scale, yet simultaneously very uniform over local regions of the distribution. WebThe null hypothesis, H 0 , for the Rayleigh’s test of uniformity is: ρ = 0 (zero concentration). For circular data the Rayleigh test statistic is: z=n r 2 =r 2 /n.

"WebThe Rayleigh match ( Rayleigh, 1881) is a traditional tool for classifying color vision. Typically, an observer is shown a circular, bipartite field of less than 2-deg diameter. One half-field contains a near-monochromatic yellow light ( ca. 590 nm), while the other contains a mixture of red ( ca. 679 nm) and green ( ca. 545 nm) light. " - Rayleigh test in r
