- if you have a genuine comment, send us an email to let us know it is in there - or just email it to one of us and we are happy to post it for you.
- we will continue to never approve a spam comment, so stop wasting your and our time spammers.
A pre-analysis plan is a step-by-step plan setting out how a researcher will analyze data which is written in advance of them seeing this data (and ideally before collecting it in cases where the researcher is collecting the data).
