tf.contrib.distributions.TransformedDistribution.log_cdf()

tf.contrib.distributions.TransformedDistribution.log_cdf(value, name='log_cdf')

Log cumulative distribution function.

Given random variable X, the cumulative distribution function cdf is:

log_cdf(x) := Log[ P[X <= x] ]

Often, a numerical approximation can be used for log_cdf(x) that yields a more accurate answer than simply taking the logarithm of the cdf when x << -1.

Args:
  • value: float or double Tensor.
  • name: The name to give this op.
Returns:
  • logcdf: a Tensor of shape sample_shape(x) + self.batch_shape with values of type self.dtype.
