Log survival function.
Given random variable X, the survival function is defined:
tfd_log_survival_function(x) = Log[ P[X > x] ] = Log[ 1 - P[X <= x] ] = Log[ 1 - cdf(x) ]
tfd_log_survival_function(distribution, value, ...)
distribution |
The distribution being used. |
value |
float or double Tensor. |
... |
Additional parameters passed to Python. |
Typically, different numerical approximations can be used for the log survival function, which are more accurate than 1 - cdf(x) when x >> 1.
a Tensor of shape sample_shape(x) + self$batch_shape with values of type self$dtype.
