Give Your Hypotheses Space! – Brian Lookabaugh

It’s tempting to throw a bunch of variables of interest into a model and evaluate each variable’s ‘impact’ on the outcome, but proceed at your own caution! Check this blog out to see why that approach is most likely not the best idea…

Significance tests, p-values, and falsificationism

This thread takes its inspiration from the recent discussions in social science and statistics about significance tests, what they’re good for, whether p-values should be banned, and what all of that has to do with general scientific methodology, particularly the Popperian one called falsificationism. See this Twitter thread for a random place to jump into the discussion. That place, however, was where @f2harrell suggested we create a thread over here. I’ll start this thread off, if I may, with...

I think it is correct to currently just classify it as “some thoughts” rather than a guidance. I still think it is useful to have a place to list possible approaches, but the text definitely needs more work. Sorry for the confusion.
