View source: R/mllaplace.R

Description

The maximum likelihood estimate of mu is the sample median while the maximum likelihood estimate of sigma is mean absolute deviation from the median.

Usage

1
mllaplace(x, na.rm = FALSE, ...)

Arguments

x

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

na.rm

logical. Should missing values be removed?

...

currently affects nothing.

Details

For the density function of the Laplace distribution see Laplace.

Value

mllaplace returns an object of class univariateML. This is a named numeric vector with maximum likelihood estimates for mu and sigma 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
