Impulse fails to start
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. The error

[Vars] package: impulse response function
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

Impulses
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

Help with graphing impulse response functions
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

Plotting labeled impulses: label collision
Dear all, As you can see from the attachment I'm using R to automatically annotate peptide fragmentation mass spectra, which are represented by impulse plots. I'd like to poll you on approaches of how to deal as generally as possible with the two biggest annotation issues I run into: 1) very close annotated masses (impulses) with similar y-axis dimensions - resulting in overlapping labels

Stardock Impulse cannot find server
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

PWGL in wine, problems
Hello, I'm new on this list. First of all, thank you to all the developers of this great project! At the moment there is only an application that keeps me on both macos and windows, its name is PWGL a free environment for computer assisted composition in openGL.

Simulate back impulse
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.

a question on impulse responses
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

Fixed-point scaling of mdf impulse response
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.

vars package, impulse response functions ??
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

Interpret impulse response functions from irf in MSBVAR library
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

"Vars" package: impulse response function
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. However I don't understand what do irf function results mean. These are the cumulative orthogonal responses

Acoustic echo cancellation
Simply to say, in a quiet room, you can play a impulse signal and then find it's impulse response signal from the microphone. For example, if the delay between the impulse signal and its response signal range from 500 to 3000 cycles, you can buffer the far-end signal to 0-300 cycles and set the filter length to 4000. It is also called to align far-end signal and near-end signal. BTW: Speex
