This function does not estimate the scale parameter for the `BetaPrime`

distribution. Transforms the data and uses `stat::nlm`

to estimate
the parameters of the Beta distribution.

## Arguments

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

- na.rm
logical. Should missing values be removed?

- ...
passed to

`mlbeta`

.

## Value

`mlbetapr`

returns an object of class`univariateML`

.
This is a named numeric vector with maximum likelihood estimates for
`shape1`

and `shape2`

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 Beta prime distribution see BetaPrime.

For `type`

, the option `none`

is fastest.
