Also, forcing people into slavery to have them learn about Clinical Statistics is proving harder than I initially thought.

But at last we had a look at Hypothesis Testing. And it was a meeting that left me totally knackered, in part because we have changed the format and this one was a bit more like imparting a Seminar, rather than a typical each-man-for-himself.

So today we had an Introduction to Clinical Statistics.

Well, this meeting went very well!

The minutes of the Expectation-Maximization (EM) algorithm are available on the Argonauts website, as usual.

Absolutely pants. Worst meeting ever. We didn’t get anywhere, we got lost into details so we will have to repeat it again, if possible with more people.

We saw how to use Markov Random Fiels to calculate the priors in a Bayesian framework. Um, we didn’t quite finish it, but all this is very interesting and suddenly many things that we have seen before, like Kalman Filters come together.

We saw Bayes’ Theorem, and Maximum Likelihood (ML) and Maximum a Posteriori (MAP) estimates, a way to combine information from different sources.

We did Self-Organizing Maps (SOMs), a way to visualize high-dimensional data using a neural network devised by T. Kohonen in 1982.
