Tests for Predictive Relationships Between Time Series Variables: A Monte Carlo Investigation
用蒙特卡罗方法比较不同检验方法在分析经济变量间预测关系时的统计性质，帮助研究者选择更可靠的检验。
Abstract Bivariate time series models have been used extensively to analyze the relationship between pairs of economic variables. Various tests have been proposed that can be used to examine the adequacy of specific models. The empirical literature is noteworthy for the frequency with which different authors using different tests reach different conclusions, and for the apparent lack of evidence for certain relationships strongly suggested by economic theory. The objective of this study is to use Monte Carlo methods to examine the size and power of alternative tests, and to relate these findings to the analytical structure of the tests.
