## Statistics second slides This is the next chapter of my Statistics course, definitely more standard, with some notions on statistical models, limit theorems, and exponential families. In the first class, I recalled the convergence notions with no proof but counterexamples and spend some time on a slide not included here, borrowed from Chris Holmes’ talk last Friday on the linear relation between blood pressure and the log odds ratio of an heart condition. This was a great example, both to illustrate the power of increasing the number of observations and of using a logistic regression model. Students kept asking questions about it.

Nice slides. I’ve glimpsed only at the first twenty ones. Regarding Slutsky’s lemma, I would prefer the “couple” version: if \$X_n\$ tends in distribution to the law of \$X\$ and \$Y_n\$ tends in distribution to a constant \$c\$ (equivalently in probability) then the couple \$(X_n,Y_n)\$ tends in distribution to the law of the couple \$(X,c)\$.
