Geometric

greybox.distributions.dgeom(q, prob=0.5, log=False)[source]

Geometric distribution probability mass function.

Parameters:

  • q (array_like) – Quantiles (non-negative integers, number of failures before first success).

  • prob (float) – Probability of success.

  • log (bool) – If True, return log-probability.

Returns:

Probability mass values.

Return type:

array
