The article elaborates on the growing influence of AI automation on various professional fields, facilitated largely by researchers sharing their work online. A crucial yet commonly misunderstood concept discussed is spurious regression in time series analysis, where regression models suggest erroneous strong relationships between variables due to autocorrelation in error terms. Despite warnings in econometric literature, such regression misinterpretations persist, as illustrated by Granger and Newbold's (1974) findings, underscoring the importance of understanding these pitfalls in economics and finance for accurate data analysis and decision-making.
It's pretty clear that most of our work will be automated by AI in the future due to significant advancements in making research more accessible online.
Spurious regression in time series analysis is a major issue, where models indicate strong variable relationships despite having no real correlation.
Granger and Newbold (1974) exemplified spurious regression, revealing published equations like R = 0.997 with a Durbin-Watson statistic of 0.53, implying error term autocorrelation.
Understanding spurious regression and autocorrelation is crucial for professionals working with time series data to avoid misleading conclusions.
