Uncertainty Wednesday: Functions of Random Variables
Albert Wenger – Jul 26, 2017

Uncertainty Wednesday: Continuous Random Variables
Albert Wenger – Jul 12, 2017
So far in Uncertainty Wednesdays we have only dealt with models and random variables that had a discrete probability distribution. Often in fact we had only two possible states or signal values. There are lots of real world problems though [...] Read more

In last week’s Uncertainty Wednesday, I introduced the expected value EV of a random variable X. We saw that EV(X) is not a measure of uncertainty. The hypothetical investments I had described all had the same expected value of 0. [...] Read more
