Hodges lehmann location shift
NettetThe Hodges-Lehmann estimate of location shift is 0.35, and the asymptotic confidence limits are 0.00 and 0.82. The confidence interval midpoint equals 0.41, which can also … NettetThe cumulative sums test is based on partial sums and therefore not robust to outlying observations. We propose a test based on the Hodges–Lehmann two-sample estimator of a location shift, which is the median pairwise difference $\operatorname{med}_{i=1,\ldots,k;j=k+1,\ldots,n} (X_i -X_j)$ , instead of the mean
