27. Analysis of breaches and co-breaks in financial series: a non-parametric approach data using high frequency. / Análise de quebras e co-quebras em séries financeiras: uma abordagem não-paramétrica usando dados de alta frequência.
This research use a non-parametric test developed by Lee &MYKLAND (2007) to extract jumps in IBOVESPA series and study its dynamics. Among the qualities of this test there are the ability to identify the exact time of occurrence of break / co-break, the sign and size of it. The jumps in the series of Dow Jones, Exchange rate, C-Bond spread and SELIC rate wer

29. Modelos mistos aditivos semiparamétricos de contornos elípticos / Elliptical contoured semiparametric additive mixed models.
Neste trabalho estendemos os modelos mistos semiparamétricos propostos por Zhang et al. (1998) para uma classe mais geral de modelos, a qual denominamos modelos mistos aditivos semiparamétricos com erros de contornos elípticos. Com essa nova abordagem, flexibilizamos a curtose da distribuição dos erros possibilitando a escolha de distribuições com cau
