Hi everyone, Recently I made an attempt at merging the tunings of GT3b1 into the official Xiph.org 1.0.1 libvorbis code. While 99% of the GT3b1 tunings are independent of 1.0.1, there is one particular value (_psy_noiseguards) which affects the whole quality range. I've chosen to use the 1.0.1 values since they changed since 1.0. Therefore, files encoded in GT3b1 mode (q 5 and above)

Hello, I'm doing a research on the impulse responses in VAR models and I'm having troubles in interpretation of R results. My question is what is the shock of impulse variable that is produced to obtain the response? Is it one-standard-deviation positive shock? If it is so how can I obtain the responses on other types of shocks, say, 10% negative shock? Thanks a lot, Marion

I have been trying to get impulse (from stardock) to work in wine. I've managed to get it installed correctly by adding dotnet20 and gdiplus from winetricks. However, when I open impulse and try to log into my account, it always says that it cannot find the server and I should check my Internet correction. I've tried using StarDock Central (which I read works) but that has the same

Hi I have a asterisk voip box connected to a classic pbx. The pbx use telecom back impulse (bad translation ?) for billing. To have all my billing done by the pbx I need to send back impulse to pbx from asterisk. Is it possible to simulate telecom back impulse with asterisk ? Thanks for your help.

Dear R users, I am using the vars package to calculate the impulse response functions and the forecast error variance decomposition of a VAR model. Unfortunately I do not know whether these functions assume unit or one standard deviation shocks. I tried to look into the code of these functions, but in vain: neither irf, nor vars::irf, nor vars:::irf output the code of the functions. Does someone

Hi, I made a small error in the impulse reponse function; when doing the inverse fft in fixed point, it will overflow unless it's properly scaled. This patch uses the same scaling as that used when updating the filters, and the outputs now have the same shape and the same scale in fixed and floating point.

Dear colleagues/contributors, I'd be pleased if someone could provide insights on how to plot impulse response functions in a format that can easily be copied in a word document just as plotting time-series of variables. I had followed the outline suggested by Benhard Pfaff [see http://127.0.0.1:17693/library/vars/html/irf.html] but I am unable to get the impulse response functions in a

Does anyone know if the bootstrap CI intervals generated by the irf() function (impulse response function) in the " vars" package are bias corrected? Thanks, Richard Saba [[alternative HTML version deleted]]

Hello, I am wondering if anyone knows how to interpret the values returned by irf function in the MSBVAR library. Some of the literature I have read indicates that impulse responses in the dependent variables are often based on a 1 unit change in the independent variable, but other sources suggest that they are based on a a change of 1 standard deviation. Any ideas which irf uses to compute the

Dear R users, I need perform structural analysis on a no intercept VAR model. Unfortunately the functions irf.VAR and dfev that come with the MSBVAR package only work with objects output by the reduced.form.var function, which seems to only evaluate VAR models with intercept. Is there a way to suppress the estimation of intercept term in reduced.form.var? Do I need to modify the code, and if I

I am fitting a reduced form VAR model using VAR in the vars library. I have several endogenous variables, and two exogenous variables. I would like to explore the effects of a shock to one of the exogenous variables on one of the endogenous variables. Using irf in the vars library only calculates the irf for the endogenous variables, this is obviously by design, is there some theoretical

So I tried to run Impulse on my Ubuntu 11.04 laptop and it installed fine (or at least seemed to). When I tried to run it I got the working cursor for a bit then nothing. I ran it in terminal and got a error message about running the Windows version of Mono so I went online and did a search for the error message and found a file called mono-2.4.2.3-gtksharp-2.12.9-win32-3.exe and ran it.

Hello, I'm using VAR models in R in order to obtain impulse responses of stock market shock on US economy. I have series of quarterly changes in real gdp, S&P 500 and quarterly level of unemployment for 1985 - 2012 period. My series are stationary. So I did all the steps below.

Hey folks, okay, here's the situation - I have a Centos 4.2 system with cups printing installed printing via postcript (with appropriate PPD file) to a HP LaserJet 1320N printer (via jetdirect socket 9100).

After playing with the vorbis code for a while and doing tons of hacks and analysis on it, I've found it to perform very poorly with impulse signals. The MDCT seems to cause lots of spreading, and it seems to result in much worse impulse performance then mp3. What is the current plan on handling this? Will a smart quantizer be able to avoid it? I've been looking at various ways of

Emscripten is an LLVM-to-JavaScript compiler. It takes LLVM bitcode - which can be generated from C/C++, using llvm-gcc or clang, or any other language that can be converted into LLVM - and compiles that into JavaScript, which can be run on the web (or anywhere else JavaScript can run). I was able to successfully build libogg, libvorbis and libvorbis examples using this tool and generate valid
