Survival function for a log-normal distribution.

Source: R/lognormal.R

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

# 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)
S(1)
#> [1] 0.5
S(2)
#> [1] 0.2441086
