similar to: package for stochastic frontier models?

Hi! A few weeks ago, I have uploaded a new R package "frontier" for Stochastic Frontier Analysis (SFA) [1] to CRAN [2]. It includes the FORTRAN code of Tim Coelli's [3] software "Frontier 4.1" [4]. Hence, the R package "frontier" should have the same capabilities as "Frontier 4.1", i.e. Maximum Likelihood Estimation of Stochastic Frontier Production

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) methods. The data

Hi, I still need to use 1.2.9-1 of OCFS2 as I have an older RHEL4 server that needs to share the filesystem. I noticed that there have been no updates and kernel 2.6.18-164.10.1 is out for RHEL5. Are you going to release updates or have you now finished with 1.2.9-1 for RHEL5? Many thanks Matt ________________________________ JPC InfoNet Limited Registered in England No.: 2983145 Registered

Hi, I am trying to find out the scale efficiency and optimal scale of banks by stochastic frontier analysis given the panel data of bank. I am free to choose any model of stochastic frontier analysis. The only approach I know to work with R is to estimate a translog production function by sfa or other related function in frontier package, and then use the Ray 1998 formula to find the scale

Hiya Compiz list! I am a Linux UI dude for VMware as my day job and am working on improving things in Workstation and Player with regards to multiple monitors on Linux. Some of my colleagues worked with the xdg/wm-spec folks just earlier this year to get the _NET_WM_FULLSCREEN_MONITORS hint into the EWMH spec to address the needs applications have in needing to be both fullscreen and spanning

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 sample selection models are often used in

Dear all, I want to program my own models about Stochastic Frontier Analysis and Linear programming (Data Envelopment Analysis). In this context, is there anyone that may help me with some simple tutorials and scripts about these issues? Thanks a lot. -- Marcus Vinicius Pereira de Souza, Prof. [[alternative HTML version deleted]]

Dear all, I want to finished my paper by latent class Stochastic Frontier Analysis , but i can not find the package, is there anyone that may help me Thanks a lot. [[alternative HTML version deleted]]

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 into the matrix I pass in. When I call the insertRow

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 heteroskedasticity is {bptest} in package

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

Dear R users, I am new to R. I would like to find *maximum likelihood estimators for psi and alpha* based on the following *log likelihood function*, c is consumption data comprising 148 entries: fn<-function(c,psi,alpha) { s1<-sum(for(i in 1:n){(c[i]-(psi^(-1/alpha)*(lag(c[i],-1))))^2* (lag(c[i],-1)^((-2)*(alpha+1)) )}); s2<- sum(for(m in 1:n){log(lag(c[m],-1)^(((2)*alpha)+2))});

I would like to calculate the mean of tree leader increment growth over 5 years (I1 through I5) where each tree is a row and each row has 5 columns. So far I have achieved this using rowMeans when all columns are numeric type and used in the calculation: Data1 <- data.frame(cbind(I1 = 3, I2 = c(0,3:1, 2:5,NA), I3 =c(1:4,NA,5:2),I4=2,I5=3)) Data1 Data1$mean_5 <- rowMeans(Data1, na.rm =T)

Hi all, I am using aidsEst( ) in "micEconAids" package to estimate Demand system. But I would like to add more demographic variables in demand system. How can I add those information? for example: mydata<-data.frame(p1,p2,p3,p4, s1,s2,s3,s4, totalexp,

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

Team, I am trying to resolve the self-selection bias of a sample in an experiment and would like to run the Heckman Correction Estimation using R. Can someone help me with the R-Code... I tried searching for the discussion, but not successful. Thanks in advance, Best, Kishore/.. http://kaykayatisb.blogspot.com [[alternative HTML version deleted]]
