Cool that makes sense. Cheers

Is this still as problematic if they regress out the weight at baseline? In this paper they don't seem to do that, rather the control of recent weight change which isn't the same thing.

Dynamic prediction with prediction of counterfactuals for individualised decisions. Really cool.

First week 'critical' to avoid children missing school later, parents told Data suggests more than half of children who miss a day at the start of term become persistently absent.

A fantastic teaching example of a predictor being misinterpreted as having a causal effect.

I also have this issue - no moderation despite preprints being available for months. It will significantly reduce the utility of psyarxiv if moderation takes the same time as peer review for an actual journal. There will be little point in submitting to preprint at psyarxiv if this is the case.

Thanks. I would love to attend but unfortunately have clinical duties at the time.

Will this be recorded and available after the webinar?
