Testing on the First-order Autoregressive Model with Contaminated Exponential White Noise Finite Sample Case
نویسندگان
چکیده
The testing problem on the first-order autoregressive parameter in finite sample case is considered. The innovations are distributed according to the exponential distribution. The aim of this paper is to study how much the size of this test changes when, at some time k, an innovation outlier contaminant occurs. We show that the test is rather sensitive to these changes.

Modified Maximum Likelihood Estimation in First-Order Autoregressive Moving Average Models with some Non-Normal Residuals
When modeling time series data using autoregressive-moving average processes, it is a common practice to presume that the residuals are normally distributed. However, sometimes we encounter non-normal residuals and asymmetry of data marginal distribution. Despite widespread use of pure autoregressive processes for modeling non-normal time series, the autoregressive-moving average models have le...
متن کاملLikelihood Analysis of a First Order Autoregressive Model with Exponential Innovations
This paper derives the exact distribution of the maximum likelihood estimator of a rst order linear autoregression with an exponential disturbance term. We also show that even if the process is stationary, the estimator is T -consistent, where T is the sample size. In the unit root case the estimator is T -consistent, while in the explosive case the estimator is T -consistent. Further, the like...
متن کاملInformation Theory Estimators for the First-Order Spatial Autoregressive Model
Information theoretic estimators for the first-order spatial autoregressive model are introduced, small sample properties are investigated, and the estimator is applied empirically. Monte Carlo experiments are used to compare finite sample performance of more traditional spatial estimators to three different information theoretic estimators, including maximum empirical likelihood, maximum empir...
متن کاملValid Resampling of Higher Order Statistics Using Linear Process Bootstrap and Autoregressive Sieve Bootstrap
Abstract. In this paper we show that the linear process bootstrap (LPB) and the autoregressive sieve bootstrap (AR sieve) fail in general for statistics whose large-sample distribution depends on higher order features of the dependence structure rather than just on autocovariances. We discuss why this is still the case under linearity if it does not come along with causality and invertibility w...
متن کاملTesting for White Noise under Unknown Dependence and Its Applications to Diagnostic Checking for Time Series Models
Testing for white noise has been well studied in the literature of econometrics and statistics. For most of the proposed test statistics, such as the well-known Box–Pierce test statistic with fixed lag truncation number, the asymptotic null distributions are obtained under independent and identically distributed assumptions and may not be valid for dependent white noise. Because of recent popul...
