tfd_log_cdf {tfprobability} | R Documentation |
Log cumulative distribution function.
Description
Given random variable X, the cumulative distribution function cdf is:
tfd_log_cdf(x) := Log[ P[X <= x] ]
Often, a numerical approximation can be used for tfd_log_cdf(x)
that yields
a more accurate answer than simply taking the logarithm of the cdf when x << -1.
Usage
tfd_log_cdf(distribution, value, ...)
Arguments
distribution |
The distribution being used. |
value |
float or double Tensor. |
... |
Additional parameters passed to Python. |
Value
a Tensor of shape sample_shape(x) + self$batch_shape
with values of type self$dtype
.
