The negative binomial distribution and Pascal’s triangle

The Poisson probability distribution gives a simple, elegant model for count data. You can even derive from certain assumptions that data must have a Poisson distribution. Unfortunately reality doesn’t often go along with those assumptions. A Poisson random variable with mean λ also has variance λ. But it’s often the

A strange take on the harmonic series

It is well known that the harmonic series 1 + ½ + ⅓ + ¼ + … diverges. But if you take the denominators as numbers in base 11 or higher, the series converges [1]. I wonder what inspired this observation. Maybe Brewster was bored, teaching yet another cohort of
