THIS IS THE CHANGELOG OF THE "micEcon" 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 0.6-14  (2017-03-16)

• added predict() methods for objects returned by quadFuncEst() and translogEst()

• moved function translogRayEst() and associated functions to a development version of a new package called micEconDist (not yet available on CRAN)

• moved functions for calculating price and quantity indices to a development version of a new package called micEconIndex (not yet available on CRAN)

• moved function logDataSet() from package "miscTools" to this package

• logDataSet() now also works for (panel) data sets that were created by pdata.frame()

        CHANGES IN VERSION 0.6-12  (2014-04-22)
  

• 'micEcon' no loger depends on package 'miscTools' but imports this package

• no panel data (e.g. cross-sectional data): fixed the returned 'model.matrix' in the presence of categorical explanatory variables

• panel data: the returned object no longer includes the 'model.matrix'

        CHANGES IN VERSION 0.6-10  (2012-06-02)
  

• internal change, not relevant for the user

        CHANGES IN VERSION 0.6-8  (2012-06-01)
  

• separated tools for non-parametric microeconomic analysis into a new package micEconNP (currently only available via micEcon's RForge site)

• added data set "appleProdFr86"

• quadFuncEst() and translogEst() now return components "r2" and "r2bar" also when a panel data model was estimated by plm()

• if the data set is a panel data frame, quadFuncEst(), and hence, also translogEst(), should call plm() rather than lm() again (the class name of panel data frames has changed)

        CHANGES IN VERSION 0.6-6
  

• translogCheckMono() now automatically removes the coefficients of shifter variables before it calls translogDeriv() so that it can be used also with models that have shifter variables now

        CHANGES IN VERSION 0.6-4
  

• removed argument "quadHalf" of many functions for econometric analysis with the translog and quadratic functional form, because this argument is confusing and not really helpful

• translogCheckMono() now can check whether a translog function is monotonically decreasing in some explanatory variables and monotonically increasing in other explanatory variables

• the "micEcon" package no longer depends on the "systemfit" package but suggests it now

        CHANGES IN VERSION 0.6-2
  

• The "micEcon" package has been split into three packages again: a) micEconSNQP (version >= 0.6-0): includes all functions and methods for production analysis with the Symmetric Normalized Profit (SNQ) function. b) micEconCES (version >= 0.6-0): includes all functions and methods for economic analysis with the Constant Elasticity of Scale (CES) function. c) micEcon (version >= 0.6-0): includes the remaining parts of the previous version of the micEcon package

• function ".micEconLogData" has been moved from the "micEcon" package to the "miscTools" package and was renamed as "logDataSet"

        CHANGES IN VERSION 0.6-0
  

• The "micEcon" package has been split into three packages: a) miscTools (version >= 0.6-0): includes miscellaneous small tools and utilities that are not related to (micro)economics, e.g. colMedians(), rowMedians(), insertCol(), insertRow(), vecli(), symMatrix(), triang(), semidefiniteness(), compPlot(), and rSquared(). b) micEconAids (version >= 0.6-0): includes all functions and methods for demand analysis with the Almost Ideal Demand System (AIDS). c) micEcon (version >= 0.6-0): includes the remaining parts of the "old" micEcon package

        CHANGES IN VERSION 0.5-23 AND BEFORE
