A UNIFIED APPROACH TO THE MEASUREMENT ERROR PROBLEM IN TIME SERIES MODELS
提出一种统一方法,用于检验短记忆、长记忆和随机游走等时间序列数据是否被白噪声污染,并发现检验功效取决于底层过程。
The measurement error problem that we consider in this paper is concerned with the situation where time series data of various kinds—short memory, long memory, and random walk processes—are contaminated by white noise. We suggest a unified approach to testing for the existence of such noise. It is found that the power of our test crucially depends on the underlying process.
