Hi all,
I am studying a paper which have a few statistical terms. I searched google
and Wikipage but didn't find a good explanation of the power and size of
hypothesis test.
What is the power and size of hypothesis test, indeed? I found these terms
are like jargons and not easy to understand.
Thank you! |

Try David Lane's HyperStat notes. Here's the chapter on power:

When you say "size", do you mean "effect size"? If so, here's another
chapter:

Power is the probability of rejecting a hypothesis. It depends on the
true parameters as well as the hypothesis you are testing.
Size is the probability of rejecting a hypothesis when the hypothesis
is true.
