Deprecated Functions in the micEcon package

Description

These functions are provided for compatibility with older versions of the micEcon package only, and may be defunct as soon as the next release.

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 ) )

   readFront41out( file = "front41.out", translog = FALSE )

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? / Is the estimated function a translog function? (not implemented in readFront41out yet).
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 an 'eta' 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.
file character variable with the name of the file to read.

Details

writeFront41in is superseded by front41WriteInput and readFront41Out is superseded by front41ReadOutput.

Value

writeFront41in writes an instruction file and an data file to disk.
readFront41out returns a list of class front41Output containing following objects:

version the version of Frontier 4.1 that produced the output.
insFile name of the instruction file used by Frontier 4.1.
dtaFile name of the data file used by Frontier 4.1.
modelType model type: either 1 for 'Error Components Frontier' or 2 for 'Tech. Eff. Effects Frontier'.
modelTypeName model type: 'Error Components Frontier' or 'Tech. Eff. Effects Frontier'.
functionType function type: either 1 for 'production function' or 2 for 'cost function'.
functionTypeName function type: 'production function' or 'cost function'.
logDepVar logical. Is the dependent variable logged.
olsResults results of the OLS estimation.
nXvars number X variables (exogenous variables of the production or cost function.
olsLogl log likelihood value of the OLS estimation.
gridResults results of the grid search.
mleResults results of the maximum likelihood estimation.
mleLogl log likelihood value of the maximum likelihood estimation.
mleCov coefficient covariance matrix of the maximum likelihood estimation.
efficiency technical efficiency estimates.
