Many of those problems require to study the independence between nonhommogeneous point processes in time, and this work develops three families of tests to assess that hypothesis. They can be applied to different types of processes, and all together they cover a wide range of situations appearing in real problems. The first family includes two tests for Poisson processes. The second family is based on the close point distance, and the third one on cross dependence functions. An extensive simulation study of the size and power of the tests is carried out and some practical rules to select the most appropriate test in different cases, are provided. The proposed tests are demonstrated on a real data application about the occurrence of extreme heat events in three Spanish locations. info:eu-repo/grantAgreement/ES/MICINN/MTM2017-83812-P info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.424 2020 STATISTICS & PROBABILITY 67 / 125 = 0.536 2020 Q3 T2 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS 96 / 112 = 0.857 2020 Q4 T3 0.626 2020 Applied Mathematics 2020 Q2 Statistics, Probability and Uncertainty 2020 Q2 Statistics and Probability 2020 Q2 Modeling and Simulation 2020 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Abaurrea, Jesús Universidad de Zaragoza (orcid)0000-0002-7974-7435 Asín, Jesús Universidad de Zaragoza (orcid)0000-0002-0174-789X 2007 265 Universidad de Zaragoza Dpto.
