tf.contrib.distributions.NormalWithSoftplusSigma.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_
