Randomness through time: stochastic processes and sample paths, Markov chains and stationary distributions, random walks and recurrence, the Poisson process, martingales and optional stopping, branching processes, Brownian motion, Itô calculus, and stochastic differential equations.
Free to start · adaptive placement finds your level · reviews timed to your own forgetting.
Every idea is taught with motivation and a worked example before the drills, and an FSRS spaced-repetition engine schedules each review for the day its model predicts you would forget it. A short placement check finds what you already know, so you start Stochastic Processes exactly where it's useful.
