Abstract

In the general two-sample testing problem $F = G$ versus $F \leq G, F \neq G$ the shift-model score function $f' \circ F^{-1}/f \circ F^{-1}$ has to be replaced by the nonparametric score function $b = \bar{f} - \bar{g}$, where $\bar{f} = d(F \circ H^{-1})/dx, \bar{g} = d(G \circ H^{-1})/dx, H = (mF + nG)/(m + n)$, and adaption of linear rank tests should be based on rank estimators of $b$. We consider an easy but rough and inconsistent rank estimator of $b$. The resulting rank test turns out to be a generalization of Galton's test. A formula for local asymptotic power under arbitrary local alternatives is derived which allows for comparison of Galton's test with every linear rank test. For various types of alternatives the Galton test is compared with the optimal linear rank test and with the Wilcoxon test. In order to get an impression of the validity of extrapolation to finite sample sizes, we included a Monte Carlo study under the same types of fixed alternatives.
