Is the labeling/naming of levels in the documentation for the predict.glmmPQL function "backwards"? The documentation states "Level values increase from outermost to innermost grouping, with level zero corresponding to the population predictions". Taking the sample in the documentation: fit <- glmmPQL(y ~ trt + I(week > 2), random = ~1 | ID, family =

I have been asked to put a club's membership form on their web, but firefox displays it as scaled to 23% and it prints at that scale. Can anyone tell me why? Thanks Anne

Hello, With some trepidation I've come to inquire about platform requirements for * after having spent a couple of hours searching and browsing the archives and skimming the Handbook (very nice). I've found recommendations for 800-1000 Mhz and 128-256 MB RAM machines. My curiosity is not about what machine I need to start using * to support live comm ops. Rather, I want to know if a

All, Apologies for cluttering the list, but I just wanted to say hello and prepare all for a barage of silly discussions from a tech-hypochondriac! We have recently purchased two servers running CentOS, and as I'm from more of a Debian based background, it would be good if someone could point out the two or three main differences please? I'm reading up on the package management as I

Hello, I am apparently confused about the use of an id parameter for an event history/survival model, and why the EHA documentation for aftreg does not specify one. All assistance and insights are appreciated. Attempting to specifiy an id variable with the documentation example generates an "overlapping intervals" error, so I sorted the original mort dataframe and set subsequent entry

Hello, I probably have a syntax error in trying to generate an expected survival curve from a weighted cox model, but I can't see it. I used the help sample code to generate a weighted model, with the addition of a "weights=albumin" argument (I only chose albumin because it had no missing values, not because of any real relevance). Below are my code with the resulting error

Hello there R-help, I'm not sure if this should be posted here - so apologies if this is the case. I've found a problem while using rle and am proposing a solution to the issue. Description: I ran into a niggle with rle today when working with vectors with NA values (using R 2.31.0 on Windows 7 x64). It transpires that a run of NA values is not encoded in the same way as a run of other

Is there an alternative to par(mfrow=c(2,1)) to get stacked scatterplot matrixes generated with "pairs"? I am using version 2.11.1 on Windows XP. The logic I am using follows, and the second "pairs" plot replaces the first plot in the current graphics device, which is not what I expected (or desired). par(mfrow=c(2,1)) pairs(b2007, main="6/2000 - 12/2006")

Is there a way to generate identical random samples using R's runif function and SAS's ranuni function?

Hello, and please advise regarding any errors/omissions on my part. However, the documentation for R's tcplot function in the evd package appears to contain an error.

Good morning all, I'm setting up Asterisk for the first time with no prior PBX experience. I'm following Andy Powell's 'Getting Started with Asterisk' (http://www.automated.it/guidetoasterisk.htm). This is my second time through that document - as I did something weird the first time and really upset it somehow - and I wanted to ask a few general questions of the list.

Hello, I would like to increase the number of iterations for running a Buckley-James regression model in the rms package, but something is apparently syntactically wrong. The following code initially is exactly as it appears in the help page (which runs successfully), then a "failure to converge" message (resulting from specifying an 'identity' link argument, the error message

I am unsure what is being returned, and what is supposed to be returned, when using 'predict' with "type='expected'" for an aftreg survival model. The code below first generates a weibull model, then uses predict to create a vector of the linear predictors, then attempts to create the 'expected' vector, which is empty. The final two steps in the code generate a

I couldn't find a direct answer in CRAN to this question, so I'm asking with some trepidation. I have a multivariate dataset (data.frame) with columns that can be expressed as a set of mixed normals (at least I think) and need to impute values that have constraints (truncated mixture of normals where the values cannot be below zero). If there isn't a package that can do this, is there
