(mass) function directly, these methods introduce an implicit bias in the representation of the data, and thus should be avoided. The survival function, on...

A likelihood function (often simply called the likelihood) measures how well a statistical model explains observed data by calculating the probability...

}f(u)\,du} is the complementary cumulative distribution function (also called survival function). The concept is named after John P. Mills. The Mills ratio...
