Testing for first order serial correlation in temporally aggregated regression models
Pereira, Pedro L. Valls - 2015
This paper shows that the LM statistic for testing first order serial correlation in regression models can be computed using the Kalman Filter. It is shown tha.t when there are missing observations, the LM statistic for this tesi is equivalent to the tesi statistic derived by Robinson (1985)...

The Effects of Structural Breaks in ARCH and GARCH Parameters on Persistence of GARCH Models
Hwang, Soosung; Valls Pereira, Pedro L. - 2009
We show that persistence of conditional volatility in large samples could be exaggerated by the existence of structural breaks in the ARCH and GARCH parameters. Our results suggest that extreme persistence frequently observed in index volatility does not necessarily indicate the same level of...

The Effects of Structural Breaks in Arch and GARCH Parameters on Persistence of GARCH Models
Hwang, Soosung; Valls Pereira, Pedro L. - 2004
We show that persistence of conditional volatility in large samples could be exaggerated by the existence of structural breaks in the ARCH and GARCH parameters. Our results suggest that extreme persistence frequently observed in index volatility does not necessarily indicate the same level of...
