Sign of the nerdiness of my colleagues: he was describing a student with passionate, constantly changing opinions of him, "her attitude could be graphed like a sine wave."
Sign of the nerdiness of me: I took (okay, gave blood for) a prenatal sceening test this morning. The doctor reminded me that it was good for ruling stuff out (if negative, 95% chance baby is fine), but not good for confirming anything (if positive, 97% of time nothing is wrong). I had to try and make this into a statistical test for my senior seminar class, if Type I error rate is 5% (5% of negatives are false negatives) and Type II error rates are 97% (97% of positives are false positives), can we determine anything about probability of underlying conditions? I don't think so unless we know the actual positive/negative reporting rates. Anyone geekier than I.
Alloicious Nukular (aka E. Mervivan Phogg) heart is beating just fine, by the way.
