Modeling and forecasting carbon dioxide emission allowance spot price volatility : multifractal vs. GARCH-type volatility models
Segnon, Mawuli; Lux, Thomas; Gupta, Rangan - 2015
price volatility, and compares their forecasting performance to the standard GARCH, fractionally integrated GARCH (FIGARCH …) and the two-state Markov-switching GARCH (MS-GARCH) models via three loss functions (the mean squared error, the mean … criteria and forecast horizons, while MS-GARCH mostly comes out as the least successful model. Applying various VaR backtesting …

Adaptive rate-optimal detection of small autocorrelation coefficient
Guay, Alain; Guerre, Emmanuel; Lazarová, Štepána - 2009
A new test is proposed for the null of absence of serial correlation. The test uses a data-driven smoothing parameter. The resulting test statistic has a standard limit distribution under the null. The smoothing parameter is calibrated to achieve rate-optimality against several classes of...

Testing for long memory against ESTAR nonlinearities
Kuswanto, Heri; Sibbertsen, Philipp - 2009
We develop a Wald type test to distinguish between long memory and ESTAR nonlinearity by using a directed-Wald statistic to overcome the problem of restricted parameters under the alternative. The test is derived from two basic model specifications where the first is the standard model based on...

Robust tests for white noise and cross-correlation
Dalla, Violetta; Giraitis, Liudas; Phillips, Peter C. B. - 2020
Commonly used tests to assess evidence for the absence of autocorrelation in a univariate time series or serial cross-correlation between time series rely on procedures whose validity holds for i.i.d. data. When the series are not i.i.d., the size of correlogram and cumulative Ljung-Box tests...
