Linear Regression
Hi, I have the following file, and I need to work out the linear regression for each sample.

ts model challenge (transfer function)
Dear useRs, I am trying to model a time series with a transfer function. I think it can be put into the ARMA framework, and estimated with the 'arima' function (and others have made similar comments on this list). I have tried to do that, but the results have so far been disappointing. Maybe I am trying to make 'arima' do something it can't... The data are time series of

Partial Credit Models using eRm
Hello all, I have just started using fitting the PCM (Partial Credit Model) using eRm and have 2 problems which I cannot solve, I have checked everywhere on the net, but no joy: Firstly, I have fit a PCM model to 10 variables with differing response categories (3 for the first 6 items, 4 for the following 2 and 2 for the last two items). mat1 <- matrix(c(rasch_bart$bart_bowel,

Comparing data
Hi all, i have a data set cintaining 14 columns and 11 rows. Rows represent single point and columns represent the parameter measured. I wiuld like to compare the data to see which are more alike. I used the cluster analysis, but now i ma wondering if there are some other methods, since the cluster analysis did not give me the result i like. I tried to use factanal() for factor analysis

assign index to colnames(matrix)
Hello, I’m trying to follow the syntax of a script from a journal website. In order to create a regression formula used later in the script, the regression matrix must have column names “X1”, “X2”, etc. I have tried to assign these column names to my matrix ScoutRSM.mat using a for loop, but I don’t know how to interpret the error message. Suggestions? Thanks, Paul

Regression query
Hi I have a set of data with both quantitative and categorical predictors. After scaling of response variable, i looked for multicollinearity (VIF values) among the predictors and removed the predictors who were hinding some of the other significant predictors. I'm curious to know whether the predictors (who are not significant) while doing simple 'lm' will be involved in

serialize() takes too long when serializing to a raw vector
Hello, R version 2.4.1 (2006-12-18) i386-pc-mingw32 Calling serialize() with a NULL connection serializes it to a raw vector. However, when the object to be serialized is large, it takes a very long time: > system.time( serialize(matrix(0, 1000, 1000), NULL) ) [1] 38.25 40.73 81.54 NA NA > system.time( serialize(matrix(0, 2000, 2000), NULL) ) [1] 609.72 664.75 1318.57 NA

Problems after performing yum update
I performed the update yesterday that included installing kernel 2.6.9-42.0.2.EL and replacing ethereal with wireshark. First, the trivial... Wireshark would not run from the KDE menu without editing the menu to change the command from "wireshark" to "kdesu wireshark" because dumpcap is at usr/sbin/dumpcap instead of /usr/bin/dumpcap . Making the change causes wireshark to

Systematically biased count data regression model
Dear all, I am attempting to explain patterns of arthropod family richness (count data) using a regression model. It seems to be able to do a pretty good job as an explanatory model (i.e. demonstrating relationships between dependent and independent variables), but it has systematic problems as a predictive model: It is biased high at low observed values of family richness and biased low at

... and the mailing list is picky about attachments... whatever you attached did not conform to the stringent requirements mentioned in the Posting Guide. Pasting the code right into the email is usually safest, though you DO have to post using plain text (as the Posting Guide indicates) or your code may get mangled by the automatic html format removal.

OK, Let's try this again! Here is the reproducible script; it is long because I had to copy the panel dataset here.
