Bootstrap ICC estimate with nested data
I would appreciate some thoughts on using the bootstrap functions in the library "bootstrap" to estimate confidence intervals of ICC values calculated in lme. In lme, the ICC is calculated as tau/(tau+sigma-squared). So, for instance the ICC in the following example is 0.116: > tmod<-lme(CINISMO~1,random=~1|IDGRUP,data=TDAT) > VarCorr(tmod) IDGRUP = pdLogChol(1)

linearHypothesis and factors
Hi everyone, I'm sure this is pretty basic but I couldn't find a clear example of how to do this. I'm running a regression, say: reg <- lm(Y ~ x1 + year) where x1 is a continuous variable and year is a factor with various year levels. Individually, each year factor variable is not significant, but I have a suspicion they are jointly significant. I can't figure out how to run

setting parameters equal in lm
Forgive me if this is a trivial question, but I couldn't find it an answer in former forums. I'm trying to reproduce some SAS results where they set two parameters equal. For example: y = b1X1 + b2X2 + b1X3 Notice that the variables X1 and X3 both have the same slope and the intercept has been removed. How do I get an estimate of this regression model? I know how to remove the intercept

Wrapper of linearHypothesis (car) for post-hoc of repeated measures ANOVA
For some time I have been looking for a convenient way of performing post-hoc analysis to Repeated Measures ANOVA, that would be acceptable if sphericity is violated (i.e. leaving aside post-hoc to lme models). The best solution I found was John Fox's proposal to similar requests in R-help: http://tolstoy.newcastle.edu.au/R/e2/help/07/09/26518.html

can't browse across subnets
Hi folks - I'm having an issue here. I have my samba server sitting on one subnet, and the rest of the clients sitting on another (due to IP administration reasons). I assign both my clients and the server to the same workgroup, but the winboxen clients can't browse to the samba server. The win clients all have WINS resolution turned on, and I specified all of my WINS servers in

Mail Merge data to a pdf file by overlaying the data on the image
Everyone, I am looking for a utility that I can use to do a mail merge of data to a pdf image file. The image file does not have any active fields, but will be just an image file. I would like to overlay names addresses etc. We currently do this with a pcl file by just overlaying the data with pcl print positions. However, in order to get the pcl file from an original pdf file we have to

SMATR common slopes test
Hi All, I am confused with SMATR's test for common slope. My null hypothesis here is that all slopes are parallel (common slopes?), right? So if I get a p value < 0.05 means that we can have confidence to reject it? That slopes are different? Or the other way around? it means that we have statistical confidence that the slopes are parallel? thanks -- Eugenio Larios PhD Student University

calculate the elasticities by linear.hypothesi commander

pcl to pdf
Everyone, I am currently using a vsifax program (pcltotiff) to convert pcl files to tiff files on a SCO Unix box, and then I am using tiff2pdf on a Centos 5.9 box to convert the file to a pdf. There are other commands that deal with multiple page tiff's and pdf's that are part of the process, but the above basic process has worked very well. The only thing I would like to enhance is a

Confidence Intervals for slopes
Hi, I'm trying to get confidence intervals to slopes from a linear model and I can't figure out how to get at them. As a cut 'n' paste example: ################# # dummy dataset - regression data for 3 treatments, each treatment with different (normal) variance x <- rep(1:10, length=30) y <- 10 - (rep(c(0.2,0.5,0.8), each=10)*x)+c(rnorm(10, sd=0.1), rnorm(10,

PCL vs. PCL 6
I am currently using samba to try and replace a windows NT box as the default print server. All is working well except for one printer driver. All drivers were installed from a win2k machine onto the samba print$ share. The problem that I'm having is with a driver for the HP laser jet 4000N printer. The PCL driver works and loads quickly. The PCL 6 driver works, but the properties

Homogeneity of regression slopes
Hello, We've got a dataset with several variables, one of which we're using to split the data into 3 smaller subsets. (as the variable takes 1 of 3 possible values). There are several more variables too, many of which we're using to fit regression models using lm. So I have 3 models fitted (one for each subset of course), each having slope estimates for the predictor variables.

using 'apply' to apply princomp to an array of datasets
Hi everyone, Suppose I have a 3D array of datasets, where say dimension 1 corresponds to cases, dimension 2 to datasets, and dimension 3 to observations within a dataset. As an example, suppose I do the following: > x <- sample(1:20, 48, replace=TRUE) > datasets <- array(x, dim=c(4,3,2)) Here, for each j=1,2,3, I'd like to think of datasets[,j,] as a single data matrix with

incl.non.slopes=FALSE does not work at predict.lm
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

Print speed with an HP Laserjet 4
I've also posted this message to the lprng list, but as I'm currently not sure where the problem lies, I'm posting it here too in the hope that someone has a clue..... I have recently installed a printer accounting system on my systems, and changed the print model for some of my users. In most cases, this has been fine, but users who are using HP Laserjet 4 printers are experiencing

Compare linear regressios for significant differences of the slopes
Hi I have (8 measures * 96 groups) = 768 datasets for which I did linear regressions using lm(). Now I want to compare the slopes for each of the 8 measures in each of the 96 groups. As I understand , I can not use > anova(lm1, ..., lm8) as the lm1 ... lm8 are based on different datasets. I also read in previous discussions in this list, that I can see if the slope +- stddev(slope)
