Write instruction file for Frontier 4.1

Description

Write an instruction file and a data file for Coelli's program Frontier 4.1 that performs stochastic frontier analysis.

Usage

   writeFront41in( data, crossSectionName, timePeriodName,
   yName, xNames = NULL, zNames = NULL,
   translog = FALSE, quadHalf = TRUE,
   functionType = 1, modelType = 1, logDepVar = TRUE, mu = FALSE, eta = FALSE,
   insFile = "front41.ins", dtaFile = sub( "\.ins$", ".dta", insFile ),
   outFile = sub( "\.ins$", ".out", insFile ) )

Arguments

data data frame that contains the data.
crossSectionName string: name of the cross section identifier.
timePeriodName string: name of the time period identifier.
yName string: name of the endogenous variable.
xNames a vector of strings containing the names of the X variables (exogenous variables of the production or cost function).
zNames a vector of strings containing the names of the Z variables (variables explaining the efficiency level).
translog logical. Should a translog function be estimated?
quadHalf logical. Multiply the quadratic terms of the translog function by one half?
functionType function type: either 1 for 'production function' or 2 for 'cost function'.
modelType model type: either 1 for 'Error Components Frontier' or 2 for 'Tech. Eff. Effects Frontier'.
logDepVar logical. Is the dependent variable logged.
mu logical. Should a 'mu' (if modelType = 1) or a delta0 (if modelType = 2) be included in the estimation.
eta logical. Should a 'mu' be included in the estimation (only if modelType = 1).
insFile name of the instruction file.
dtaFile name of the data file.
outFile name of the output file.

Value

writeFront41in writes an instruction file and an data file to disk.
