Spurious Regression
نویسنده
چکیده
The spurious regression phenomenon in least squares occurs for a wide range of data generating processes, such as driftless unit roots, unit roots with drift, long memory, trend and brokentrend stationarity. Indeed, spurious regressions have played a fundamental role in the building of modern time series econometrics and have revolutionized many of the procedures used in applied macroeconomics. Spin-offs from this research range from unit-root tests to cointegration and errorcorrection models. This paper provides an overview of results about spurious regression, pulled from disperse sources, and explains their implications.

Structural Spurious Regressions and A Hausman-Wu-type Cointegration Test∗
Economic models often imply that certain variables are cointegrated. However, tests often fail to reject the null hypothesis of no cointegration for these variables. One possible explanation of these test results is that the error is unit root nonstationary due to a nonstationary measurement error in one variable. For example, currency held by domestic economic agents for legitimate transaction...
متن کاملLocal Limit Theory and Spurious Nonparametric Regression
A local limit theorem is proved for sample covariances of nonstationary time series and integrable functions of such time series that involve a bandwidth sequence. The resulting theory enables an asymptotic development of nonparametric regression with integrated or fractionally integrated processes that includes the important practical case of spurious regressions. Some local regression diagnos...
متن کاملSpurious Regressions with Time-series Data: Further Asymptotic Results
A “spurious regression” is one in which the time-series variables are non-stationary and independent. It is well-known that in this context the OLS parameter estimates and the R converge to functionals of Brownian motions; the “t-ratios” diverge in distribution; and the Durbin-Watson statistic converges in probability to zero. We derive corresponding results for some common tests for the Normal...
متن کاملSpurious Regression in Time-Wise Autocorrelated and Cross-Sectionally Heteroskedastic Procedures
Spurious regression is a serious problem in empirical research when time series has unit roots. This problem might exist when we apply a regression procedure for pooling time series and cross-section data. There are several models to pool time series and cross-section data in regression context, e.g. fixed effect or random effect model. Recently, Entorf [1997] and Kao [1999] also pointed out th...
متن کاملThe spurious regression of AR(pp) infinite-variance sequence in the presence of structural breaks
This paper analyzes a spurious regression involving AR(p) infinite-variance processes in the presence of structural breaks by least squares using asymptotic theory. It is found that when regressing two independent infinite-variance sequence with breaks in the level and slope of trend, no matter whether the breaks occur at different points or not, the t-ratios become divergent and spurious pheno...
