Resumo: | The main objective of this work was to open a discussion on rainfall forecast models for Ceará and its macro-regions. For that, Bayesian models were analyzed, combining Generalized Linear Models (GLMs) and t-Student models with time series models. The proposed approach takes into account not only the historical series, but also dozens of covariates that, according to meteorological studies, are related to the rainfall phenomenon in Ceará. The proposed models use the LASSO algorithm for automatic model selection, in which the variables were selected through the AIC and SBC criteria. Thereafter, generalized linear models and t-Student models were fitted. ARIMA and SARIMA time series models were also fitted. The posterior estimates were obtained through stochastic simulation methods MCMC. |

Para isso, modelos bayesianos foram analisados, em que se combinaram Modelos Lineares Generalizados (MLGs) e modelos t-Student com modelos de séries temporais. A abordagem proposta leva em consideração não somente a série histórica, mas também dezenas de covariáveis que, segundo estudos meteorológicos, têm relação com o fenômeno das chuvas no Ceará. Os modelos propostos usam o algoritmo LASSO de seleção automática de modelos, em que as variáveis foram selecionadas através dos critérios AIC e SBC. A partir daí, ajustaram-se modelos lineares generalizados e modelos t-Student. Foram ajustados também modelos de séries temporais ARIMA e SARIMA. As estimativas a posteriori foram obtidas através de métodos de simulação estocástica MCMC.LASSOModelos Lineares Generalizados (MLGs)t-StudentAnálise de séries temporaisMonte Carlo via cadeias de Markov (MCMC)Modelos bayesianos para previsão de chuvas no CearáBayesian models for forecasting rainfall in Cearáinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisporreponame:Repositório Institucional da Universidade Federal do Ceará (UFC)instname:Universidade Federal do Ceará (UFC)instacron:UFCinfo:eu-repo/semantics/openAccessORIGINALdis_2023_dssilva.pdfdis_2023_dssilva.pdfapplication/pdf5280187http://repositorio.ufc.br/bitstream/riufc/70940/3/dis_2023_dssilva.pdf3a0e2bd331cfe5338170cd8ecc90b575MD53LICENSElicense.txtlicense.txttext/plain; charset=utf-81784http://repositorio.ufc.br/bitstream/riufc/70940/4/license.txt82c2f88b8007164a64e9b9207328aedfMD54riufc/709402023-03-01 11:28:33.507oai:repositorio.ufc.br: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Repositório InstitucionalPUBhttp://www.repositorio.ufc.br/ri-oai/requestbu@ufc.br || repositorio@ufc.bropendoar:2023-03-01T14:28:33Repositório Institucional da Universidade Federal do Ceará (UFC) - Universidade Federal do Ceará (UFC)false |
