ProbitBernoulli distribution.
The ProbitBernoulli distribution with probs parameter, i.e., the probability
of a 1 outcome (vs a 0 outcome). Unlike a regular Bernoulli distribution,
which uses the logistic (aka 'sigmoid') function to go from the un-constrained
parameters to probabilities, this distribution uses the CDF of the
standard normal distribution:
p(x=1; probits) = 0.5 * (1 + erf(probits / sqrt(2))) p(x=0; probits) = 1 - p(x=1; probits)
Where erf is the error function.
A typical application of this distribution is in
probit regression.

The type of the event samples. Default: |
validate_args |
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. |
allow_nan_stats |
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. |
