Schnauzer Mug

I'm a big fan of my coffee mug that features a weird interlocking pattern of Schnauzers. I'm drinking out of it right now.

I'm behind. I have homework to do.

Here's a glimpse into the kind of homework I get. For stats, part of our homework is to critique an NBER (National Bureau of Economic Research) paper linking autism and television watching. We're supposed to focus on their use of precipitation rates as an instrumental variable for television watching. We need to assess whether or not precipitation is a good instrument (correlated with the variable it's instrumenting, but no independent correlation with the dependent variable).

Better get on it.
