Day off work today. And what better way to spend it than in study? Concentrated study. In front of the computer, concentrating, ignoring all distractions, soaking up knowledge, learning the difference between sensitivity and specificity in relation to the performance of a binary test. I kid you not.
So far, I've hung up some washing, emptied the dishwasher, eaten breakfast, drunk tea, checked facebook, and twitter, looked at pictures of snow, checked out a couple of music festivals this summer, made another cup of tea, checked emails, fed the cats, blogged ...
... and found some curvy photos
