[R] [R-pkgs] micEcon split into micEconSNQP, micEconCES, and micEcon
In December, the packages "miscTools" and "micEconAids" were separated from the "micEcon" package. Now, two further packages have been separated from the micEcon package: "micEconSNQP" and "micEconCES". The "micEconSNQP" package (version 0.6-2) provides tools for production analysis with the Symmetric Normalized Quadratic (SNQ) profit function (also known as the "Generalized McFadden" profit function), e.g. snqProfitEst() for estimating the SNQ profit function, snqProfitCalc() for calculating the endogenous variable of the SNQ profit function, or snqProfitEla() for calculating price elasticities of the SNQ profit function. The "micEconCES" package (version 0.6-6) provides tools for estimating the Constant Elasticity of Scale (CES) function. Function cesEst() has been tremendously improved. It can estimate the CES function using much more estimation methods (optimizers) now, e.g. the Levenberg-Marquardt or the Differential Evolution algorithm. Furthermore a "vignette" (supplementary documentation) "Estimating the CES Function in R: Package micEconCES" (written by Geraldine Henningsen and Arne Henningsen) [1] has been added. The "micEcon" package (version 0.6-2) includes the remaining parts of the "old" micEcon package, e.g. for economic analysis with Cobb-Douglas functions, translog functions, quadratic functions, or linearly homogeneous non-parametric functions. All these packages are available on CRAN [2,3,4] and R-Forge [5].
