What is it about?

We have compared methods for estimating how much one time series 'influences' another, in a simple system containing two simultaneously observed components. We have investigated performance on a number of simulated datasets, as well as providing tests for their robustness to problems with data.

Why is it important?

Understanding cause-and-effects in observational time series data is a difficult challenge, involving contributions from different areas of mathematics. There is not an easy one-size-fits all solution to this problem, which requires careful consideration of other additional potential causes or confounding variables. Our work is a step towards this goal, via a greater understanding of which tools (and when) are suitable for quantifying relationships in a bivariate system.
