26/02/2018 · This structured-tutorial teaches what stationarity and spurious regression are all about using Excel package. It also shows how to detect if a series is nonstationary, or when a regression is spurious and what must be done to correct for such. The tutorial also covers empirical testing with augmented Dickey-Fuller (ADF)

SPURIOUS REGRESSIONS WITH TIME-SERIES DATA FURTHER

A well-known case of a spurious relationship can be found in the time-series literature, where a spurious regression is a regression that provides misleading statistical evidence of a linear relationship between independent non-stationary variables.

Regression Analysis > Spurious Correlation. What is a Spurious Correlation? A spurious correlation wrongly implies a cause and effect between two variables. For example, the number of astronauts dying in spacecraft is directly correlated to seatbelt use in cars: Use your seatbelt and save an astronaut life! This graph — showing that an increase in car seat belt results in a lower number of

SPURIOUS REGRESSIONS WITH TIME-SERIES DATA FURTHER

• Q: How do we detect a spurious regression (between I(1) series)? - Check the correlogram of the residuals. - Test for a unit root on the residuals. • Statistical solution: When series are I(1), take first differences. Now, we have a valid regression. But, the economic interpretation of the regression changes. . When series are I(0), modify the t-statistic: Spurious Regression

How to detect heteroscedasticity and rectify it

Our strong correlation blends together the concept of ordinary or weak regression - indeed, an improved, robust, outlier-resistant version of ordinary regression (or see my book pages 130-140) - together with the concept of X and Y sharing similar bumpiness (or see my book pages 125-128).

This possibility of a ‘spurious relationship’ between variables in economics, particularly in macroeconomics and finance, restrains the form of model that can be used. An error-correction model will provide a solution in some cases.
