mllogis {univariateML}

Logistic distribution maximum likelihood estimation

Description

Calculates the estimates using nlm with an exponential transform of the location parameter.

Usage

mllogis(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 logistic distribution see Logistic.

Value

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
