Kernel-based portmanteau diagnostic test for ARMA time series models
In this paper, the definition of the Toeplitz autocorrelation matrix is used to derive a kernel-based portmanteau test statistic for ARMA models. Under the null hypothesis of no serial correlation, the distribution of the test statistic is approximated by a standard normal using the kernel-based normalized spectral density estimator, without having to specify any alternative model. Unlike most ...
متن کاملA Conditional Goodness-of-Fit Test for Time Series
This paper proposes a uni ed approach for consistent testing of linear restrictions on the conditional distribution function of a time series. A wide variety of interesting hypotheses in economics and nance correspond to such restrictions, including hypotheses involving conditional goodness-oft, conditional homogeneity, conditional mixtures, conditional quantiles, conditional symmetry, distribu...

متن کاملMixed Portmanteau Tests for Time-series Models
This paper obtains the joint limiting distribution of residuals and squared residuals of a general time-series model. Based on this, we propose a mixed portmanteau statistic for testing the adequacy of fitted time-series models. In some cases, it is shown that this statistic can be simply approximated by the sum of well-known portmanteau statistics. The finite-sample performance of the new test...
