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...

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, 1...

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 taking care of this, and before I bother implime...

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 single gr...

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 2) very close annotated masses with widely differing y-...

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 usi...

I am just studying Asterisk now and have a question. Is it possible to force anyone who enters a queue into voice mail after they have been in the queue for 30 seconds? /************************************************************** Ken Alker ken@impulse.net ham radio: KA6SDU Impulse Internet Services http://www.impulse.net Santa Barbara, San Luis Obispo, Ventura, Los Angeles, Orange T-3 / T-1 / ADSL / ISDN / 56K / web hosting / wireless / co-lo ***************************************************************/

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. (http://www2.siba.fi/PWGL/) I'm running Ubuntu 8.04 and wine 0.9.59. I have to say that I also installed vcrun2005 and

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 cod...

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. Best regards, Thorvald...

As an aside, if you know how to make a Cisco 7960 running SIP send a "flash" command (SIP, RTP, or otherwise), I'd really like to know. /************************************************************** Ken Alker ken@impulse.net ham radio: KA6SDU Impulse Internet Services http://www.impulse.net Santa Barbara, San Luis Obispo, Ventura, Los Angeles, Orange T-3 / T-1 / ADSL / ISDN / 56K / web hosting / wireless / co-lo ***************************************************************/

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 irf? The documentation is not very clear. Thanks, Spencer [[alternat...

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'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...

None of the lag variables of the Turkish stock exchange determine foreign stock exchange; however, lag values and spot values of the foreign stock exchange affect Turkish stock exchange movement. To calculate the standard errors of the impulse response functions, I should use the modified error bands of Bernanke, Hall, Leeper, Sims and Zha (1996) for the maximum likelihood estimation (MLE).

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-...
