Riddler screencast: simulating a branching process

If a post gets spam replies at an average rate of one per day, but then every reply gets its own spam replies at the same rate, how many replies could we expect on average after three days?

This demonstrates simulation of stochastic processes with rexp() and cumsum(), and shows how we can go from simulation results to closed-form mathematical solutions.

Great video David. I've just found your channel. Is there a place where your videos can be watched live? Thank you!
