WebSpurious means that there is some hidden variable or feature which causes both of the variables. In both time-series and in usual regression then terminology means the same, the relationship between two variables is spurious when something else causes both variables.

WebInappropriate inference of causality is referred to as a spurious relationship (not to be confused with spurious correlation ). Correlation only reveals a relationship between variables but not the context; the presence of a third factor that accounts for the association between variables is a confounding variable.

Example: Spurious correlation In …
In statistics, a spurious relationship or spurious correlation is a mathematical relationship in which two or more events or variables are associated but not causally related, due to either coincidence or the presence of a certain third, unseen factor (referred to as a "common response variable", "confounding factor", or "lurking variable").
Web22 Feb 2024 · It could be that this correlation simply occurs by chance.
