```Hi

in order to have the parameters of X i have apply ar(x,n) the result is an
idpoly like that:
A(q)y(t) = e(t) A(q) = 1 - 1.582 q^-1 + 0.7303 q^-2 .

first i don't know how to extract the parameters i guest that here
parameters are[1,1.582,0.7303] if it’s true how can i extract them?

second i have to reconstitute my original signal X using the calculate
parameters witch command matlab should i use?

please i really need help.

```

AR model order
Hi, I am a student doing a project in DSP. My signals measure the blood volume pulse changes at three different stages. So i have 3 different signals for each subject. I am using the AIC model order selection criteria for selecting the model order but I am having sum issues with calculating the total squared error. Isnt it the difference between the signal and the mean. Also, when I plot graph of AIC vs Model order to see where the graph minimizes, I get differnet values for different signals for the same stage of different subjects. How can I choose one specific model order for each stage so ...

AR/ARMA models on filtered data
I was just wondering whether it makes sense to apply an AR or ARMA model to pre-filtered data. I am working on EEG data pre-filtered in the 8-12Hz band and wanted to model this data using an AR or ARMA model but in the literature it seems that everybody applies AR modelling on the raw data. Is there anything wrong with this? Am I to expect that the model for the filtered data would better include a MA part to better model the new filtered spectrum? From my experience, model order estimation techniques seem to opt for an MA model in this case. Thanks in advance. ...

Fitting AR model to stohastic signal
Hi I have a sample of a Stohastic signal with very slowly variable mean, and would like to find AR model for it perhaps using Burg parameter estimation model (explained in book by Kay). I would like to try diffent model order until I get the Power spectral density of white noise driven AR model's output, to look like the PSD of my sample. Is the aforementioned possible?(any other ideas?) Also can I expect AR model's ouput(to white noise) in time to resemble my Stohastic sample provided PSDs 'match'?

How to predict a value of a timeseries using an AR(1) model?
Hi, I've got a series of numbers a(1),a(2),a(3)...a(n). Using an AR(1) model, I would like to predict the value of a(n+1). I'm trying to write my own program for this, but I'd just like to make sure I'm doing the right thing by cross-checking my results with some built-in Matlab functions. I guess I should use "aryule(x,p)" for this. Now I understand, that since I want to use an AR(1) model, then p should be 1, i.e. aryule(x,1). But what am I supposed to enter in x? If I've got a list of 6 numbers: x = [13.4 13.7 12.6 13.1 12.2 12.9] Do I place this x into ar...

how to model poisson / logit model using proc model?
Dear all, Is there anyway to model poisson or logit model using proc model in ets? I think it is doable given the power of proc model. Could you please shed some light on it?

VoIP traffic Modeling
Hi, I am trying to implement VoiP traffic model but I don´t understand one thing! frcatel.fri.uniza.sk/users/smiesko/publikacie/clanok3.pdf this above is document on which Markov model I am trying to generate VoIP traffic. On page 200. you can see how the human voice should look like, and on page 203. is the Markov model based on Exponential distribution. My problem is with this ON/OFF states! In ON it generates traffic and in OFF it doesnt, so it is 0. So it should switch from for instance 64 kbps and 0 kbps. But how can I make this beacuse ON and OFF transitions are modele...

Relational model versus object model
Hello everybody, Every now and then, a question pops-up on this forum, that initiates the discussion on how the relational model relates to the object model, and how one of them is better (or worse) than the other. While being an OOD believer (I've been working in C++ for more than 10 years) I do think that it is quite difficult sometimes to ensure data integrity by "chasing pointers" that connect objects. Besides, if you want to boost performance, you often have to introduce redundancy, because no data structure fits perfectly to every possible usage. Handling redundancy by ...

Non linear model fitting with an integral model
Hello, I'm new user of Mathemetica. I'm trying to fit data to a model, that is defined by an integral, using NonlinearModelFit. The integral contains the parameter I'm looking for. When I set a particular value for the parameter, NIntegrate works well giving an estimate of the integral value; but when I define the model within the fitting algorithm, the integral cannot be numerically evaluated since it contains the non-numerical parameter giving the "inumr" error message. Do anyone know how to fit data with model parameters contained in an integral that must be numericall...

Model-in-the-loop, running two models together
I have (not really yet) two simulink models at separate files. those models consist of a subsystem block and some stuff inside the subsystem blocks. I would like to run these two models together so, that output of model 1 is connected to input of model 2 and output 2 to input 1 (this is model-in-the-loop -simulation) How could I do this? Of course I could create a new blank model and copy-paste the models into it and connect the ports but I am looking for some other way because this way is slow to do very often when developing my models. Lots of routine work to repeat again and again. Antho...

Model fit for ordinal multinomial models in GENMOD?
Hi I have been fitting models for two response variables, one ordinal and one normal (using AIC to choose the "best" model). For the normal data I can evaluate model fit and assumptions as usual, and by looking at residual plots. However, as I understand it, residuals are not available for ordinal multinomial models in GENMOD. How do I then best assess fit and if I meet the model assumptions? This is the first time that I'm analyzing ordinal multinomial models, so maybe I'm missing something obvious. thanks Tobias Jeppsson ...

Interest in conceptual data modeling (fact-based modeling)?
Folk, I've long been interested in fact-based data modelling, also known as conceptual modeling, using the technique of Object Role Modeling (see http://www.orm.net). An algorithm called RMap is known which maps an ORM model to a relational model, and is implemented in some existing tools - for example NORMA, an open source Visual Studio plugin, at <http://sourceforge.com/projects/orm>. The fact-based modeling process reliably creates correct database schemas by dealing in elementary facts, delaying and automating decisions about how to group those fact into tables and columns unti...

Re: Model fit for ordinal multinomial models in GENMOD?
Tobias, It is somewhat of a multi-step process, namely first determine if the cumulative logit model assumption is OK with LOGISTIC: PROC LOGISTIC DATA=indat; CLASS xvar / PARAM=glm; FREQ count; MODEL y = xvar / link=clogit ; run; Near the top you'll see: The LOGISTIC Procedure Score Test for the Proportional Odds Assumption Chi-Square DF Pr > ChiSq 3.9106 3 0.2713 which the relatively "large" pvalue indicates the cumulative logit model works To assess goodness of fit for the clogit model and a categorical explanatory variable, you can...
