#statstab #308 A Tutorial on Safe Anytime-Valid Inference [t-test]

Thoughts: Useful functions for psychologists. I like how it treats t-tests, giving all the options from Lakens (2013) for Cohen's d, and comparison with other software.

When is the t-test appropriate?
▶️ In short, the t-test is needed when P values are required and there are no nuisance variables to control for nor covariates to adjust for.
In practice, having no nuisance variables/covariates to adjust for is relatively rare situation.
