Bob has tweeted, but it’s worth a quick post. His 90 min new-statistics zoomfest was part of SIPS2020. More than 100 folks, almost all staying to the end. Excited and positive chat all the way through. Yes, a 5am start …
Just had an update about Fiona’s big project to study how well researchers can judge the chance that some result can be replicated. She and the team are doing well, but need a last push during July to meet their …
