similar to: Bootstrapping on R

Hi, I am new to R (I have most of my experience in SAS and SPSS). I was wondering if anyone has used both Resampling Stats and R, and could comment on strengths/relationships. Also, I have no clue on how to do the various examples from the book "Resampling: The New Statistics" in R. Can anyone give me some possible starting points? Or websites/books? Thanks, Brandon

To whom it may concern: I just would like to know how can one generate a set of random values from the double exponential distribution. Thanks. Jason Parcon

Hello everyone, I am trying to use the 'find.BIB' function to construct a balanced incomplete block design. When I ran the example given in the help file (find.BIB(10,30,4)), I obtained the following error message: Error in optBlock(~., withinData = factor(1:trt), blocksize = rep(k, b)) : object ".Random.seed" not found I investigated what the optBlock

Hello, I downloaded R today because I was told it has very good bootstrapping abilities. What I need to do is to program it (or use an existing program) to bootstrapping test for multimodality using nonparametric kernel density estimates as proposed by Efron and Tibshirani (1993). If anyone can get me started, I will be immensely grateful. Thanks. Sangeeta

Hello All, Despite my preference for reporting confidence intervals, I need to obtain a p-value for a hypothesis test in the context of regression using bootstrapping. I have read John Fox's chapter on bootstrapping regression models and have consulted Efron & Tibshirani's "An Introduction to the Bootstrap" but I just wanted to ask the experts here for some feedback to make

To whom it may concern: Is there a function that we can use to easily obtain the rank of a matrix in R? Thank you very much. Jason Parcon --------------------------------- [[alternative HTML version deleted]]

HI All, I am trying to analyse the results of a heap of samples, to determine how many samples are required to meet a defined confidence interval. I checked out the R manual for bootstrapping and re-sampling methods, but did not find anything. Are there any contributed procedures that deal with this? thanks, Matt Redding Soil Scientist Intensive Livestock Environmental Management-Research

Dear Sirs, I am a R beginning user: by mean of R I would like to apply the bootstrap to my data in order to test cost differences between independent or paired samples of people affected by a certain disease. My problem is that even if I am reading the book by Efron (introduction to the bootstrap), looking at the examples in internet and available in R, learning a lot of theoretical things on

Hi All: I have to compute bootstrap confidence intervals, the statistic (incremental cost effectiveness ratio) is computed from two samples (intervention and control) of different sizes. All the bootstrap functions that I have seen use one dataset as argument. I may go ahead and get the desired number of bootstrap replications separately. I would appreciate if you could point me to a source of a

Hola! Tengo que hacer un proyecto acerca del paquete bootstrap de R, alguien podría facilitarme información completa (y en español a ser posible) acerca de este paquete? Muchas gracias de antemano, y un saludo. [[alternative HTML version deleted]]

I need to construct confidence intervals for the binomial variance. This is the usual estimate v = x*(n-x)/n or its unbiased counterpart v' = x*(n-x)/(n-1) where x = binomial number of successes observed in n Bernoulli trials from proportion p. The usual X^2 method for variance confidence intervals will not work, because of the strong non-normal character of the sampling

I want learn permutation test and resampleing, etc. There are a few references listed below. I'm wondering what is the best book on this topic. Can somebody give me some advice. Thank you! http://en.wikipedia.org/wiki/Resampling_%28statistics%29#Permutation_test

Dear all, I want to install R-0.65.0 on mips-sgi-irix6.5 (SGI IRIX 6.5 IP32), but it doesn't work !!!

I have a vague recollection of seeing a R-function that will output a table or matix in a format suitable for the tabular enviroment in LaTeX. But I cannot find it. Any hints?

Hello all, I am currently working with rpart to classify vegetation types by spectral characteristics, and am comming up with poor classifications based on the fact that I have some vegetation types that have only 15 observations, while others have over 100. I have attempted to supply prior weights to the dataset, though this does not improve the classification greatly. Could anyone supply some

I've looked through the documentation with R-0.64.1 and have been unable to find a high-level function for evaluation of factorials (i.e., n!, not factorial designs). Is there such a function? It is trivial to code, so everyone could write their own, but it also would be worthwhile as a standard tool. I'm guessing I am just overlooking it.
