About statistical analysis #23

Thank you so much for your presentation! I am interested in the part of statistical analysis. In the paper, the Jackknife test is used to measure latency differences. Is there any specific reason that you chose this test? Why is it powerful in this study? Is there any other methods that could be helpful? Thank you so much!

The jacknife test is a nice way to evaluate latency effects in relatively noisy data. It is similar to a bootstrapping analysis, in that many different ensembles of data are inspected to see if the aggregate pattern is reliable across a convincing subset of the participants. to summarize, it's a way to evaluate the reliability of the latency effect and the degree to which it is expected to generalize across lots of people, instead of being driven by a subset of subjects.
