similar to: Fitting a GLM: Problems with ns & date functions

(My apologies if this is a repeated posting. I couldn't find any trace of my previous attempt in the archive.) I'm having trouble with forecast() in the dse2 package. It works fine for me on a model without a trend, but gives me NaN output for the forecast values when using a model with a trend. An example: # Set inputs and outputs for the ARMA model fit and test periods

Hi, I cannot find a 'vectorized' solution to this 'for loop' kind of problem. Do you see a vectorized, fast-running solution? Objective: Take the value of X at each timepoint and calculate the corresponding value of Y. Leading 0's and all 1's for X are assigned to Y; otherwise Y is incremented by the number of 0's adjacent to the last 1. The frequency and

Greetings, I am working on a platform for analysis automation. I need to run several Virtual Environments concurrently and record information about their behavior. I wrote some months ago about the capability of reading the Memory during the Environment's execution (in paused state). What do I need is the complete linear memory image, byte per byte, nothing special; I will give this output

Dear R users I want to compute Kendall's Tau between two vectors x and y. But x and y may have zeros in the same position(s) and I wrote the following function to be sure to drop out those "double zeros" "cor.kendall" <- function(x,y) { nox <- c() noy <- c() # for (i in 1:length(x)) if (x[i]!= 0 | y[i] != 0) nox[length(nox)+1]<- x[i] for (i in

Dear all, I want to use the "rearrange" command which is based on Chernozhukov et al paper and is included in the quantreg package. So, I run a quantile regression in which I included dummy variables for state and years in order to estimate the respective fixed effects quantile regression. The problems are the followings: 1. At example that is stated in the help****, I don't

So we got an Ubuntu 10.10 VPS, and go there with SSH putty, working with Xming as X server. This is what we did so far, to host a dedicated nox server. Code: apt-get update sudo apt-get install wine sudo apt-get install xorg wget *noxinstall url* unzip noxinstall.zip wine NoxInstall.exe (an installer and we put it in /root/Nox/) Wine wouldn't recognice a CD, so a crack gets installed

hi, I'm using OpenSuSE 11.1 with wine version 1.1.9 downloaded from the repositories. Nox is a game from Westwood that I used to play using wine until recently... It required a CD to be played so I mounted it's image and linked it in to the dosdevices directory in ~/.wine. After doing that the game ran fine. However, I was running out of space on my HOME partition so i used Gparted live

Hello I am trying to use all subsets regression on a test dataset consisting of 11 trails and 46 potential predictor variables. I would like to use Mallow's Cp as a selection criterion. The leaps function would provide the required output but does not work with this many variables (see below). The alternative function regsubsets should be used, but I am not able to define the function in

I'm working with data measured in a tunnel to estimate the emission factor of heavy & light vehicles. I tried to use 'gnls' and I get the following Error: >> Error in "coef<-.corARMA"(*tmp*, value = c(174.267493382104, 173.412740072763 : >> Coefficient matrix not invertible Here is my R-code: data <- d.plabutsch.neu # calculating the starting

I have obtained from transfer functions, the state space matrices for the following state space model. x* = Ax + Bu y = Cx + Du I have A, B, C, and D, now I would like to take the exogenous inputs and simulate the data using the state space model. I know there is a simulate function in the package dse1, but I am unsure as to what type of TSmodel to create to put into it. Could anyone give me

Dear all, I am trying to estimate the prediction from a fixed effects model and their confidence intervals as well. Though I do not want to include in the prediction and at the confidence intervals the intercept. For that reason I used the argument incl.non.slopes=FALSE. But either if it is TRUE or FALSE it does not have any difference and also the system does not provide any warning. I really

Dear list I'm plotting ( boxplot() and plot() ) some data for a publication. The editor would like the text labels on the plots in a larger font. I'm doing something like this: <snip> jpeg( filename = "D:/Martin/Work/CleanPath/RAF1%03d.jpg", width = 1000, height = 600, pointsize = 12, quality = 100, bg = "white", res = 96, restoreConsole = TRUE )

Hi: (Tried to find a bug report about this issue, but was unable to find it, let me know if this is a known issue) I have been working on an interface to highlight xyplot panels on mouse overs in JavaGD but I have stumbled with what seems to be a bug in trellis.focus. I am using JGR R 2.8 with lattice 0.17-15 Note: It's important to you use JGR to use the Java Graphics Device. *** To

I am trying to install an old game called Nox in Linux under WINE. I have tried running setup.exe from both the main directory as well as from the setup directory. The screen goes black and I get a box with "DirectX Error" as a title and the message is "Action not supported". Can someone tell me how to fix that ... I see that others have gotten Nox to run with out this error

I ran the following script from xyplot Examples using Tin-R on Windows and saw no plot produced. EE <- equal.count(ethanol$E, number=9, overlap=1/4) xyplot(NOx ~ C | EE, data=ethanol, prepanel = function(x,y) prepanel.loess(x, y, span=1), xlab="Compression Ratio", ylab="NOx (micrograms/J)", panel = function(x,y) { panel.grid()(h = -1, v=2)

Hi all, I'm trying to find a way to get xyplot to produce a second set of axes outside the right hand side of the graph. This is my progress so far: EE <- equal.count(ethanol$E, number=9, overlap=1/4) xyplot(NOx ~ C | EE, data = ethanol, prepanel = function(x, y) prepanel.loess(x, y, span = 1), xlab = "Compression Ratio", ylab = "NOx (micrograms/J)",

I need to split a data frame into 3 columns. The column I want to split contains indices of lag (prefix L1 or L2 and suffix 01, 03, 04), station name (shown in the sample data as capitalized G, P and S) and pollutant name. Names with no ?L? prefix or 01/04 suffix are lag 0. Lag 01 is average of lag 0 and 1, and 04 is average of 0 to 4 days. How can one do that in R? I will ignore the other
