Abstract in Portuguese
O objetivo deste trabalho é propor um novo método para obtenção das estimativas dos coeficientes do modelo GARCH, considerando que eles variam ao longo do tempo. Além da metodologia proposta também foram apresentados modelos GARCH tradicionais com coeficientes fixos no tempo. Ambos os modelos foram testados em 3 séries reais: retornos do Ibovespa, Vale e Itaú com o objetivo de verificar se o fato de considerar coeficientes variando no tempo ajuda a melhorar a capacidade preditiva do modelo.
