Non linear discriminant based on mixture of distributions: an application in return time of heterogeneous maximum flows observed in the Paranapanema river basin-Brazil
Descripción del Articulo
In this work, maximum flows observed in the Paranapanema river basin are modeled by a mixture of two GEV distributions whose components correspond to the summer and winter subpopulations. The nonlinear discriminant function allowed to confirm the assumption of mixture model.The proposed model is the...

A funcao discriminante nao linear permitiu confirmar a hipótese do modelo de mistura. O modelo proposto é entao usado para determinar as probabilidades de excedencias e períodos de retorno associados a vazoes extremas, que sao de fundamental importancia para projetos hidráulicos. Os resultados mostram diferencas significativas quando um modelo de mistura é usado e, portanto, uma abordagem mais coerente com os dados observados.National University of Trujillo - Academic Department of Mathematics2020-12-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.unitru.edu.pe/index.php/SSMM/article/view/3079Selecciones Matemáticas; Vol. 7 No. 02 (2020): August - December; 242-249Selecciones Matemáticas; Vol. 7 Núm. 02 (2020): Agosto-Diciembre; 242-249Selecciones Matemáticas; v. 7 n. 02 (2020): Agosto-Diciembre; 242-2492411-1783reponame:Revistas - Universidad Nacional de Trujilloinstname:Universidad Nacional de Trujilloinstacron:UNITRUporhttps://revistas.unitru.edu.pe/index.php/SSMM/article/view/3079/3932Derechos de autor 2020 Selecciones Matemáticasinfo:eu-repo/semantics/openAccessoai:ojs.revistas.unitru.edu.pe:article/30792022-10-21T18:50:04Z |
