[R] simulation in vector autoregressive model (VAR)

I have a data from 4 variables ( STOCK, CPI, EXC, and CCI) from 1980 to 2012. I want to do a forecast using VAR(12) model with a simulation of 100,000 for 5 years. And also estimate the RMSE, MAPE, and Theil Inequality. Can anyone help me with this problem in R? Thanks so much.

This is a major point... do not make the mistake that you can "get by" using MSWord as a text editor because it actively changes your code in ways that make sense in a word processor but change code in ways that corrupt it.

[R] Gamma count

I intend to simulate data from gamma distribution. I plan rounding the observations into counts. What I want to know is how I will manipulate the parameters of gamma to have both over and under dispersed count scenarios. [[alternative HTML version deleted]]

Hi Ragia, I can't make out your data or desired result, but it sounds like aggregate() might get you started. If you need more help, please repost your data using dput() and do NOT post in HTML so that we can see what your desired result looks like. Sarah On Fri, Sep 4, 2015 at 10:12 AM, Ragia

Dear John, Very many thanks. Your hypothesis was completely correct - I did save the workspace, and this is what created the problem. As a newbie, being part way through an "exercise", saving my workspace intuitively seemed the right thing to do. Clearly not!So now, before I closed R

Re: [R] Visualization of people's interactions by participation to parties

Hendrik, It's not clear to me what kind of R help you are looking for. I suggest you provide more information on the data that you have and the questions that you want answered. Is it in an external file? Is it an R object? What code have you written or tried? Including example data, for

Re: [R] Visualization of people's interactions by participation to parties

Hendrik, As a start, I'd make a matrix of zeros with the parties in rows and all of the participants as columns and put a one for each participant at each party. The matrix will consist of a vector for each participant showing the parties attended. The pattern may suggest the next step.

Re: [R] simulation in vector autoregressive model (VAR)

Before you post on Rhelp you should first read the Posting Guide. It tells you that requests for statistical advice might be answered but are not really on-topic. Furthermore requests for tutorials or extended worked examples should probably be accompanied by evidence of searching using Google

[R] getting a vector of unown size

Hi all! I have written some code in C for simulating the fate of population using a dll loaded in R. During this simulation the population may go extinct such that the length of its trajectory is unknown beforehand. I wonder there is a way to define the size of the result in C and make it

Re: [R] getting a vector of unown size

If you had read the Posting Guide as every posting admonishes you in the footer, you would know that this question about C belongs on R-devel, not R-help. I think a lot of C questions are addressed in the Writing R Extensions document also, so be sure to convey how the documentation failed to

Re: [R] Gamma count

Pick the mean (mu) and variance (sig2) you want. Then, shape = mu^2/sig2 and scale = sig2/mu. This should work fine if your mean is large enough so that p(x = 0 or 1) is small. -- View this message in context: http://r.789695.n4.nabble.com/Gamma-count-tp4711845p4711853.html Sent from the R
