mlinvweibull: Inverse Weibull distribution maximum likelihood estimation

Description

The maximum likelihood estimate of shape and rate are calculated by calling mlweibull on the transformed data.

Usage

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

Value

mlinvweibull returns an object of class

univariateML. This is a named numeric vector with maximum likelihood estimates for shape and 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

Arguments

x

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

na.rm

logical. Should missing values be removed?

...

passed to mlweibull.

Details

For the density function of the log normal distribution see InverseWeibull.
