摘要：
An analog of the Rayleigh test is developed for weighted vector data. [The data are from migratory Ipswich sparrows (Passerculus sandwichensis princeps) captured in mist nets and tested briefly in activity cages.] 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 resultant lengths are tabulated.
