#statstab #489 On the performance of the Neyman Allocation with small pilots
Thoughts: If you know your treatment condition will have larger variance you can optimise your sample size.

#statstab #487 More than meets the ITT: A guide for anticipating and investigating nonsignificant results in survey experiments
Thoughts: I see a lot of papers that make at least one of the 7 errors for "no effect".

#statstab #476 Experimental : causal
Thoughts: Randomized experiments are the gold standard for inference for a reason. But they are hard to design.

#statstab #463 One-and-a-half sided test
Thoughts: Alberson has a more different take on the issues from #461 and #462: human behaviour.

In an hour and a half (12:30 UTC / 14:30 CET) I'll give a lightning talk at the online BTS conference about the tool we are putting together for standardizing hypotheses.

We're working on a tool for standardizing hypothesis formulation. We've put together a bibliography of previous work on the topic. Are we missing any important papers?

#statstab #413 Counternull Sets in Randomized Experiments
Thoughts: The counternull is a lost statistic, that is woefully underused when teaching stats.

The National HIV Story Trust has an exciting opportunity for someone to join the HIVstory project based at #TheLondonArchives on a paid archives placement.
Full details on the role and how to apply are below 👇

A big thank you to @jisc.bsky.social, @britishlibrary.bsky.social and The National Archives for such a fantastic conference. It was the perfect space to promote the work of the #NHST team, their project, and their incredible collection held by us at TLA. Visit us and take a look yourselves!
🧵 4/4
#NHST have deposited 103 full-length recordings with #TheLondonArchives, documenting the lived experience of the epidemic, including people living with HIV, carers, partners, relatives, friends, and healthcare practitioners. As part of the #PositiveHistory Project, these can be viewed at TLA.

We made a trip to @durham-university.bsky.social for #DCDC25. Among the many panels was an incredible keynote speech by the co-founders of the National HIV Story Trust, set up to film, record and preserve the history of those affected by the HIV/AIDS epidemic of the 1980s and 90s. #NHST 🧵 1/4
Unfortunately, when we do null hypothesis significance testing #NHST with #p-values and the like, which is still the default approach in most disciplines, we do not know whether a lack of statistical significance means no true effect, or there is simply not enough evidence. 2/3
