The Geometric distribution is parameterized by p, the probability of a positive event. It represents the probability that in k + 1 Bernoulli trials, the first k trials failed, before seeing a success. The pmf of this distribution is:
tfd_geometric(
logits = NULL,
probs = NULL,
validate_args = FALSE,
allow_nan_stats = TRUE,
name = "Geometric"
)Floating-point Tensor with shape [B1, ..., Bb] where b >= 0
indicates the number of batch dimensions. Each entry represents logits
for the probability of success for independent Geometric distributions
and must be in the range (-inf, inf]. Only one of logits or probs
should be specified.
Positive floating-point Tensor with shape [B1, ..., Bb]
where b >= 0 indicates the number of batch dimensions. Each entry
represents the probability of success for independent Geometric
distributions and must be in the range (0, 1]. Only one of logits
or probs should be specified.
Logical, default FALSE. When TRUE distribution parameters are checked for validity despite possibly degrading runtime performance. When FALSE invalid inputs may silently render incorrect outputs. Default value: FALSE.
Logical, default TRUE. When TRUE, statistics (e.g., mean, mode, variance) use the value NaN to indicate the result is undefined. When FALSE, an exception is raised if one or more of the statistic's batch members are undefined.

a distribution instance.
Mathematical Details
pmf(k; p) = (1 - p)**k * p
where:
p is the success probability, 0 < p <= 1, and,
k is a non-negative integer.
