Power analysis for astronomers

Stephen Senn (2002) explains the need for statistical power analysis.

“An astronomer does not know the magnitude of new stars until he has found them, but the magnitude of star he is looking for determines how much he has to spend on a telescope.”

Senn, S. J. (2002). Power is indeed irrelevant in interpreting completed studies. BMJ, 325, 1304–1304
