Bayes' theorem, also called Bayes' rule or Bayesian theorem, is a mathematical formula used to determine the conditional probability of events. The theorem uses the power of statistics and probability ...

The stock market is an ever-changing place. In fact, it’s changing every second of every day as prices go up and down, and new factors impact the trajectory of the market. It’s important for investors ...

Rev. Thomas Bayes (1702-1761), an English clergyman, is credited as the author of “An Essay Towards Solving a Problem in the Doctrine of Chances.” Published posthumously in 1763, the paper set out ...

Bayes Theorem is a way to calculate conditional probabilities. This is important when you want to calculate how probabilities change when you see data. It is a way to measure how much you have learned ...

Our eyes, gestures, and tone bring us together in a more profound way than words alone. It’s why we look hopefully toward the return of in-person, face-to-face connection. In science, progress is ...

Having a strong opinion about an issue can make it hard to take in new information about it, or to consider other options when they’re presented. Thankfully, there’s an old rule that can help us avoid ...

Over the years, many writers have implied that statistics can provide almost any result that is convenient at the time. Of course, honest practitioners use statistics in an attempt to quantify the ...

Although Bayes's theorem demands a prior that is a probability distribution on the parameter space, the calculus associated with Bayes's theorem sometimes generates sensible procedures from improper ...
