โœฆ Synopsis


We consider tests for the equality of prediction mean squared errors and for forecast encompassing. It is shown that, if forecast errors exhibit ARCH, size distortions are induced in the usual tests. Adjusted test statistics are suggested to alleviate this problem.

In this paper we investigate the properties of the Lagrange Multiplier [LM] test for autoregressive conditional heteroscedasticity (ARCH) and generalized ARCH (GARCH) in the presence of additive outliers (AOs). We show analytically that both the asymptotic size and power are adversely aected if AOs

A test of forecast rationality based on the weak eciency of ยฎxed-event forecasts was proposed by Nordhaus (1987). This paper considers the scope for pooling ยฎxed-event forecasts across `events', to deliver more powerful tests of the weak-eciency hypothesis, when only a small number of ยฎxedevent fore

## Abstract We consider asymptotic behavior of selfโ€normalized sums of autoregressive fractionally integrated moving average (ARFIMA) processes whose innovations are GARCH errors. The asymptotic distribution of the sums is derived under very mild conditions. Applications to unit root tests with ARF
