Now, two further packages have been separated from the micEcon package: "micEconSNQP" and "micEconCES".

The "micEcon" package has been split into three packages: miscTools, micEconAids, and micEcon. 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(),...

Dear R Users: The functions of our "micEcon" package [1,2] can be subdivided into three categories: - microeconomic demand and firm models - sample selection models (mainly selection()) - routines for (likelihood) maximisation (e.g. maxLik(), maxNR(), maxBHHH()) (mainly used for ML estimation of sample selection models) Although sa...

Dear R Users: We have splitted up the micEcon package into three packages: a) Package "maxLik" provides tools for maximum likelihood estimations (see http://www.maxLik.org). b) Package "sampleSelection" provides tools for estimating Heckman-type sample selection/generalized tobit models (see http://www.sampleSelection.o...

Dear R users, I would like to inform you that everything of the "micEcon" package that is related to Stochastic Frontier Analysis (SFA) has been moved to the "frontier" package, because this is a more appropriate place for the functions "front41WriteInput", "front41ReadOutput", and "front41Est", and the corresponding (S3)...

Hi, R core team I am using the function {aidsEst} in package [micEcon] to do an AIDS model now. So far, everything is good. But I want to test the auto correlation and heteroskedasticity of the individual equation from AIDS demand system. How can I return the individual equation? PS: serial correlation test is {bgtest} in package [lmtest] and heteroskedasticit...

Dear all, In the search for a command to insert a row between other rows in a data frame I found that there seems to be no such command in the base R package. There is however a very simple function insertRow in the micEcon package, that makes use of rbind. I wondered if it would not be possible to include the following micEcon functions in the base package: insertRow insertCol Since the functions are already there, I would gather this is not a very big effort. It would save people that just want to insert rows an...

Hello all, I am trying to use the micEcon 'insertRow' function inside a function I have written. For example: insert_row_test <- function(m){ insertRow(m,nrow(m)+1,v=0,rName="test") } However, when I try to call the 'insert_row_test' function (after loading the micEcon package), it does not insert a row i...

Dear all, I have uploaded a new package called micEcon (version 0.1-3) to CRAN (an early version of this package has been already presented at useR! 2004). It contains tools for microeconomic analysis and microeconomic modeling. These are for instance: - tools for demand analysis with the 'Almost Ideal Demand System' (AIDS): e.g. econometric...

I need to estimate maximum tree crown radius and am looking for a package to prepare stochastic frontier models in R. I have not found any package references on Nabble R help, google, or R help. Any tips on a package for this? With regards, Aaron Trowbridge Researcher BV Research Centre Smithers B.C. -- View this message in context:

Dear All, we (Ott Toomet and I) would like to add functions for maximum likelihood (ML) estimations of generalized tobit models of type 2 and type 5 (*see below) in my R package for microeconomic analysis "micEcon". So far we have called these functions "tobit2( )" and "tobit5( )". Are these classifications well known? How are these functions called in other software packages? Should we keep these names or does anybody have better suggestions? (* T. Amemiya (1984): Tobit models...
