In the shower this morning, I was thinking about how seldom true longitudinal designs meet the assumption of sphericity. This is the point where one of my daughters always makes a comment about what other people think about in the shower. I don’t want to hear it. Sphericity is an assumption that all correlations among…
If you are the right age to have watched re-runs of the show on Nickelodeon, Clarissa Explains It All, then you are the age group today’s blog was written for. And don’t tell me the previous statement is grammatically incorrect. After having looked at these results, I’m already pissed off (note to self: don’t swear…
Hispanic, female, Ph.D. statistician who loves math. Hoo-wee, we hit the lottery! Let’s have her come talk to our inner city school children about STEM education. It’ll be SO uplifting. Ri-i-ight.

I was at a conference recently when someone asked me what I was passionate about and I answered, “Data”. He seemed very disappointed and wandered off in search of someone more interesting who would give a better answer like curing AIDS or ending world hunger or solving global warming. I could have added , “and…

In this competition, ten finalists are selected to give a 90-second pitch on their start-up.
