Changes in version 0.6-20 (2025-10-06)                 

    o   the internal functions .quadFuncCheckHomWeights() and .quadFuncVarHom() are
	no longer exported

    o   minor improvements in the documentation

                 Changes in version 0.6-18 (2022-09-03)                 

    o   clarified a warning message in predict.quadFuncEst()

    o   updated the reference output of a test script due to changes in the "plm"
	package

                 Changes in version 0.6-16 (2021-01-06)                 

    o   added data set "utility"

                 Changes in version 0.6-14 (2017-03-16)                 

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

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

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

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

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

                 Changes in version 0.6-12 (2014-04-22)                 

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

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

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

                 Changes in version 0.6-10 (2012-06-02)                 

    o   internal change, not relevant for the user

                        Changes in version 0.6-8                        

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

    o   added data set "appleProdFr86"

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

    o   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 (2010-08-12)                  

    o   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 (2010-05-25)                  

    o   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

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

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

                 Changes in version 0.6-2 (2010-03-15)                  

    o   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

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

                 Changes in version 0.6-0 (2009-12-28)                  

    o   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
