Hi, after having tested SFA in august, I didn't use it for some times and now I receive the subject error when calling through Skype channel. Has anyone an idea on what can be the problem? Thanks -- Daniel

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 and Cost Fun...

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 sets "riceProdPhil" and "Coelli&qu...

...I suspect this is a very basic query. I have a data frame structured "flat" (i.e. separate observations for a given subject ID on separate lines). Using the nlme library I create a groupedData object suitable for further analysis thus: dataset <- groupedData(VARIABLE ~ TIME|ID, data=sfa) The dataset has a large number of VARIABLES of interest so I want to make use of loops where possible to build groupedData objects from each of the relevant columns along the lines of: sfa <- na.omit(read.csv("SFAFinalData.csv", header = TRUE)) factorsList <- colnames(sfa) noFac...

Anyone connected up to it yet? http://www.skypeforsip.com/ It would seem to make Digiums chan_skype rather pointness, or am I missing something? Or is this Digiums chan_skype in a hosted box somewhere? Gordon

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 efficiency. However, as the textbook Coelli et al 2005 point out that the concavity may not be satisfied, one needs to impose the nonpositive definiteness condition so that the scale efficiency <1...

...5 per month per channel just to test the beta! I find that insane, but I wanted to test it. In October, they will begin charging for Skype Manager (required for SfS) and a per seat charge for that. My guess is that the one channel would cost me about $15/month. For our use, I'd much rather use SfA. You can test SfS is you like by just registering a SIP phone to their servers. That's what I am doing now. I haven't tested outgoing calls to SKype names, but they are possible. Probably, like OpenSkY they are made using numbers in a table that equate to Skype names. /r

Hello, I work on the Stochastic Frontier Analysis (SFA) and I am looking for a function in a R package which done the multivariate interpolation. My problem is: For all i=1, ..., n, I have values of (xi1, xi2, ..., xi7)in IR^7 and f(xi1, xi2, ..., xi7)in R and I have also values of (x'i1, x'i2, ..., x'i7) in IR^7 and I need f(x'i1, x&...

Hi, As many remember, almost one year this Skype for Asterisk extension program was announced. Has anyone tried it ? Is there any available pricelist ?

Hi, what is the state at this time for 64bits applications and compatibility with 1.6.2 Mainly speaking about FFA, SFA, G729. Thanks for any information -- Daniel

Is there anything special that has to be done to make video calls work? It doesn't seem to work for me (no video). What CODECS are supported?

...d Skype For Asterisk beta software. This is a "time-expiring" beta - the software will stop working on August 31. The download is also currently time-limited - it will be available until August 7 on our website. After the 31st, you would need to have purchased a license for the SfA software (sorry, no pricing that I can give you right now - that will be a separate announcement. I'm just the community guy - I have no idea about pricing or commercial contracts or the like, so please wait until that's been announced as I will find out about the same time as you...

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]]
