Method to obtain the inverse cdf of an exponential object.

Method to obtain the inverse cdf of an exponential object.

# S3 method for class 'exponential'
inv_cdf(x, ...)

Arguments

x

The object to obtain the inverse cdf of

...

Additional arguments (not used)

Value

A function that computes the inverse cdf of the exponential distribution. Accepts as input a vector p probabilities to compute the inverse cdf, a rate value denoting the failure rate of the exponential distribution, and a logical log.p indicating whether input p denotes probability or log-probability. By default, rate is the failure rate of object x.

Examples

x <- exponential(rate = 1)
q <- inv_cdf(x)
q(0.5)
#> [1] 0.6931472
q(0.95)
#> [1] 2.995732
