THIS IS THE CHANGELOG OF THE "micEconCES" PACKAGE

Please note that only the most significant changes are reported here.
A full ChangeLog is available in the log messages of the SVN repository
on R-Forge.


            CHANGES IN VERSION 0.9-0   (2011-05-23)

* all CES function can account for technological change now

* cesEst() can estimate CES functions by assuming that the error term is 
multiplicative (i.e. taking the residuals from the logged model)

* cestEst() additionally returns a named scalar/vector that contains the 
constant elasticity/elasticities of substitution and print.cesEst() now prints 
the constant elasticity/elasticities of substitution

* summary.cestEst() additionally returns the covariance matrix of the constant 
elasticity/elasticities of substitution and changes object "ela", which is a 
matrix with four columns now (elasticities of substitution, std. err., 
t-values, P-values) and print.summary.cesEst() now prints the constant 
elasticity/elasticities of substitution, as well as the corresponding 
std. errors, t-values, and P-values

* the 3-input nested CES function has no longer coefficient "gamma_1", because 
it is obsolete and cannot be identified in econometric estimations

* renamed some coefficients of the 3-input and 4-input nested CES functions

* added data set "GermanIndustry"

* the package vignette now additionally describes the features regarding the 
3-input and 4-input CES functions



            CHANGES IN VERSION 0.8-0   (2010-12-13)

* added support for nested CES functions with 3 or 4 inputs


            CHANGES IN VERSION 0.6-8

* reduced execution time of the examples by removing several examples and by
decreasing the number of iterations in the (example) estimations that use the
SANN and the DE algorithm


            CHANGES IN VERSION 0.6-6

* fixed a bug in the package vignette


            CHANGES IN VERSION 0.6-4

* added a "vignette" describing this package; it has the title "Estimating
  the CES Function in R: Package micEconCES" and it was written by Geraldine
  Henningsen and Arne Henningsen

* the test scripts cesTest.R, cesTestGrid.R, and rhoFixed.R as well as
  the corresponding output files have been excluded from the R package
  (using .Rbuildignore) to reduce the execution time of "R CMD check"
  on CRAN (these scripts are still included in the SVN repository)


            CHANGES IN VERSION 0.6-2

* initial release of this package

* the function "cesEst", its documentation, and the test script
  have been moved from the "micEcon" package to this package

* function "cesCalc" for calculating the endogenous (output) variable
  of the CES function has been added

* a lot of features (e.g. estimation methods), (S3) methods, and test scripts
  have been added
