WebDec 1, 2024 · The generalized Cucconi test statistic In this section, we propose a generalized two-sample Cucconi test statistic, namely C p, q, with p, q ∈ R + for the two-sample location–scale problem. At first, define that S p = def. ∑ i = 1 N i p, T q = def. ∑ i = 1 N ( N + 1 − i) q, ST p, q = def. ∑ i = 1 N i p ( N + 1 − i) q. WebMay 2, 2024 · Dixon’s Q Test, often referred to simply as the Q Test, is a statistical test that is used for detecting outliers in a dataset.. The test statistic for the Q test is as follows: Q = x a – x b / R. where x a is the suspected outlier, x b is the data point closest to x a, and R is the range of the dataset. In most cases, x a is the maximum value in the dataset but it …

In statistics, the Cucconi test is a nonparametric test for jointly comparing central tendency and variability (detecting location and scale changes) in two samples. Many rank tests have been proposed for the two-sample location-scale problem. Nearly all of them are Lepage-type tests, that is a combination of a location test and a scale test. The Cucconi test was first proposed by Odoardo Cucconi in 1968.
