In algebraic.dist: Algebra over Probability Distributions

Survival function for a log-normal distribution.

Description

Returns a function that computes S(t) = P(X > t) for the log-normal distribution.

Usage

## S3 method for class 'lognormal'
surv(x, ...)

Arguments

x	A lognormal object.
...	Additional arguments (not used).

Value

A function function(t, log.p = FALSE, ...) returning the survival probability (or log-survival probability) at t.

Examples

x <- lognormal(0, 1)
S <- surv(x)
