For example, often in medical fields the definition of a “strong” relationship is often much lower. spurious correlation A correlation between two variables when there is no causal link between them. An example 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.
