Testing the equality of a large number of U-estimable parameters.
M. Romero Madroñal, M. R. Sillero Denamiel, M. D. Jiménez Gamero
The problem of comparing a parameter, estimable through U-statistics, across k populations is addressed. The kernel is assumed to have degree two. A statistic is proposed, shown to be distribution-free under the null hypothesis and certain alternatives for large k. This property under the null allows for the construction of a test, while the distribution under alternatives enables a power analysis. The finite performance of the test is numerically assessed through a simulation study.
