Notes

The probability mass function for geom is:

for $k\ge 1$, $0<p\le 1$

geom takes $p$ as shape parameter, where $p$ is the probability of a single success and $1-p$ is the probability of a single failure.

Note that when drawing random samples, the probability of observations that exceed np.iinfo(np.int64).max increases rapidly as $p$ decreases below $10^{-17}$. For $p < 10^{-20}$, almost all observations would exceed the maximum int64; however, the output dtype is always int64, so these values are clipped to the maximum.
