Background Artificial intelligence ECG (AI-ECG) models can predict cardiovascular outcomes, but their clinical adoption is limited by restricted access to training data and uncertain generalisability.

Test automation is one of the most critical parts of software development life cycle nowadays because of its great advantages like, more coverage for testing processes, reliability and efficiency.

The z-test and t-test power computation NormalIndPower and TTestIndPower give much smaller sample sizes than using samplesize_proportions_2indep_onetail. I don't see where the differences come from.

Trying to do a one-sample Z test for a proportion. In R, this would be: > prop.test(1200, 2500, p=0.44, correct = F) 1-sample proportions test without continuity correction data: 1200 out of 2500, ...
