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 0.6-18 (2022-09-03) * clarified a warning message in predict.quadFuncEst() * updated the reference output of a test script due to changes in the "plm" package CHANGES IN VERSION 0.6-16 (2021-01-05) * added data set "utility" 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 * please take a look at the log messages of the SVN repository on R-Forge
