Questions & Answers

This section contains answers to frequently asked questions (FAQ's) about alpha.

Spotlight

How can I check my false-positive rate and is it right?

It is often thought that a false-positive rate (FPR) of 5% is somehow 'correct', because a 5% FPR is commonly used in the literature as a standard when comparing the performance of different screening tests. However, the correct FPR for your population will not necessarily be the same as the published estimates. It will depend on a number of factors, including the age distribution, which may differ from the age distribution of the standard populations used in scientific papers.

How To's

Some questions are better answered by a guide so we have provided a series of guides on how αlpha works and changes are made within the program.
