getsurvival: Survival Probability
In ROCit: Performance Assessment of Binary Classifier with Visualization

Function getsurvival calculates survival probability from an object of class "density" at specified value.

1	getsurvival(x, cutoff)

`x`	An object of class "density".
`cutoff`	Value at which survival probability will be calculated.

The survival function S, of a random variable X is defined by,

S(X=x) = 1 - F(X=x)

where F is the cumulative density function (CDF) of X.

Survival probability.

getsurvival is used internally in other function(s) of ROCit.

data("Loan")
k <- density(Loan$Income)
# What portion have income over 100,000
getsurvival(k,100000)
