front41Est {frontier}

Estimate a Stochastic Frontier Model by Frontier 4.1

Description

Estimate a stochastic frontier model with a modified version of Tim Coelli's program Frontier 4.1 (NOTE: this program has to be installed separately!).

Usage

   front41Est( command = ifelse( .Platform$OS.type == "windows",
      "front41.exe", "front41.bin" ), ... )

Arguments

command

command to call the modified version of FRONTIER 4.1 (see details).

...

arguments passed to front41WriteInput.

Details

Using the command front41Est requires the installation of a modified version of Tim Coelli's FRONTIER 4.1. It is available on http://frontier.r-forge.r-project.org/front41.html. as (FORTRAN) source code and (executable) binaries for GNU/Linux and MS-Windows.

Value

front41Est returns a list of class front41Output that is returned by front41ReadOutput with two additional elements:

input

object returned by front41WriteInput.

messages

messages returned by FRONTIER 4.1.
