Unlike the classical GEV, this model can represent data with two modes and heavy tails, offering much greater flexibility. We built a regression framework linked to the median of the distribution, making interpretation more intuitive. Parameters are estimated using maximum likelihood, and performance is evaluated through Monte Carlo simulations. Finally, applying the model to real climate data from Brazil shows that it accurately captures extreme and bimodal patterns, providing a robust and efficient alternative to traditional mixture models.<\/p>\n<p><strong>Data: 18\/11\/2025<br>Hor\u00e1rio: 14:00<\/strong><\/p>\n<p>O semin\u00e1rio acontecer\u00e1 na<strong>&nbsp;modalidade Online<\/strong>&nbsp;e poder\u00e1 ser assistido pelo link: https:\/\/mconf.ufrgs.br\/webconf\/ppgest<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Temos o prazer de convidar a todos para mais um semin\u00e1rio do Programa de P\u00f3s-Gradua\u00e7\u00e3o em Estat\u00edstica da UFRGS (PPGEst-UFRGS).
