The maximum likelihood estimate of rate is the inverse sample mean.

## Usage

mlexp(x, na.rm = FALSE, ...)

## Arguments

x

a (non-empty) numeric vector of data values.

na.rm

logical. Should missing values be removed? If FALSE, the function fails when x contains missing values.

...

currently affects nothing.

## Value

mlexp returns an object of classunivariateML. This is a named numeric vector with maximum likelihood estimates for rate and the following attributes:

model

The name of the model.

density

The density associated with the estimates.

logLik

The loglikelihood at the maximum.

support

The support of the density.

n

The number of observations.

call

The call as captured my match.call

## Details

For the density function of the exponential distribution see Exponential.
