Return Value

The survivor distribution function (SDF) is the complement of the cumulative distribution function (CDF). The function gives the probability that a sample from the distribution will be greater than or equal to the specified value.

This method is particularly useful for calculating upper tail probabilities, as round-off error is avoided.
