Title: | On the automatic selection of the tuning parameter appearing in certain families of goodness-of-fit tests | Authors: | Tenreiro, Carlos | Keywords: | goodness-of-fit tests; data-based tuning parameter selection; calibration; normality tests; empirical characteristic function; exponentiality tests; empirical Laplace transform | Issue Date: | 2019 | Publisher: | Taylor and Francis | Serial title, monograph or event: | Journal of Statistical Computation and Simulation | Volume: | 89 | Issue: | 10 | Abstract: | The situation, common in the current literature, is that of a whole family of location-scale/scale invariant test statistics, indexed by a parameter $\lambda\in\Lambda$, is available to test the goodness of fit of $F$, the underlying distribution function of a set of independent real-valued random variables, to a location-scale/scale family of distribution functions. The power properties of the tests associated with the different statistics usually depend on the parameter $\lambda$, called the ``tuning parameter'', which is the reason that its choice is crucial to obtain a performing test procedure. In this paper, we address the automatic selection of the tuning parameter when $\Lambda$ is finite, as well as the calibration of the associated goodness-of-fit test procedure. Examples of existing and new tuning parameter selectors are discussed, and the methodology presented of combining different test statistics into a single test procedure is applied to well known families of test statistics for normality and exponentiality. A simulation study is carried out to access the power of the different tests under consideration, and to compare them with the fixed tuning parameter procedure, usually recommended in the literature. | URI: | https://hdl.handle.net/10316/87197 | DOI: | 10.1080/00949655.2019.1598409 | Rights: | embargoedAccess |
