If X(1), X(2), ..., X(n) are independent random variables, not necessarily with the same distribution, what is the variance of Z = X(1) X(2) ... X(n)? It turns out that the computation is very simple:

In particular, if all the expectations are zero, then the…

Fun Math: Infinite Nested Radicals of Random Variables - Connection with Fractals and Brownian Motions

Some original and very interesting material is presented here, with possible applications in Fintech. No need for a PhD in math to understand this article: I tried to make the presentation as simple as possible, focusing on high-level results rather than technicalities. Yet, professional statisticians and mathematicians, even academic researchers, will find some deep and fascinating results worth further exploring. Source code and Excel spreadsheets are provided for replication…

Simulated Stock Market: Original Gaming App Played with Real Money

I wrote earlier in 2019 an article entitled New Stock Trading and Lottery Game Rooted in Deep Math, see here. It features a number guessing game that -- depending on the parameters -- mimics either a neutral stock market or a lottery. The gain depends on the distance between your guess and the winning numbers. The average gain is zero, and…
