Hi,
Could anyone point me towards an explanation of the difference between Sensitivity (as described here: http://en.wikipedia.org/wiki/Sensitivity_and_specificity) and Statistical Power?
I'd assumed the two terms were synonyms, until I read this on the above mention Wikipedia page:
"In the traditional language of statistical hypothesis testing, the sensitivity of a test is called the statistical power of the test, although the word power in that context has a more general usage that is not applicable in the present context."
Many thanks for any advice you can give!
Simon
