Their courage will be the catalyst for lasting change, provided all of us turn this into a sustained effort. Having been in tech for over two decades as an […] Read more (opens Continuations in a new tab)
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. It is trivial, given a random variable with EV(X) = μ to construct […] Read more (opens Continuations in a new tab)

In today’s Uncertainty Wednesday we start to explore the properties of random variables. The first one we will look at is the so-called “expected value” or EV for short. The EV is simply the probability weighted average of a random variable X, i.e. EV = ∑P(x)*x sum is for all possible values x that […] Read more (opens Continuations in a new tab)
