[Recall that in its simplest form Hodges’ estimator for the mean of an N(µ,1)-distribution is given by the arithmetic mean ¯y of the random sample of size n if y¯ exceeds the threshold n−1/4, and is given by zero otherwise.] Now, as is well-known, e.g., from Hodges’ example, the oracle property is an asymptotic ...

In statistics, the Hodges–Lehmann estimator is a robust and nonparametric estimator of a population's location parameter. For populations that are symmetric about one median, such as the (Gaussian) normal distribution or the Student t-distribution, the Hodges–Lehmann estimator is a consistent and median-unbiased estimate of the population median. For non-symmetric populations, the Hodges–Lehmann estimator estimates the "pseudo–median", which is closely r… Nettet5. jan. 2024 · 2.
