Bernoulli random variables are random variables that take one of two values. For convenience, let us represent these values are $1$ and $0$. So, formally a Bernoulli ...

In this session, to solidify our understanding of hypothesis testing distributions, we construct those distributions and see how they derive from the normal distribution. The Introduction to ...

This step, in particular, calls on and tests the applied econometrician’s skill and experience. The main tool of the fourth stage is hypothesis testing, a formal statistical procedure during which the ...
