Hello, I have a simple class that looks like: setClass("statisticInfo", representation( max = "numeric", min = "numeric", beg = "numeric", current = "numeric", avg = "numeric", obs = "vector"

...stical computing". I think of it as writing programs or functions, such as R or packages in R, and of understanding the numerical analysis behind these functions. I exclude USING computer programs, such as R, for data analysis from my definition of statistical computing. I see that as doing statistics. I have had students, some sent by other faculty members, in my class on statistical computing thinking they were going to learn how to do statistical analysis using the computer. There was a clash of expectations between what they thought they were taking and what I had in the syllabus. Rich --...

The Statistical Computing and Graphics Award The ASA Sections of Statistical Computing and Statistical Graphics have established the Statistical Computing and Graphics Award to recognize an individual or team for innovation in computing, software, or graphics that has had a great impact on statistical practice or research. Typically, awards are granted bi-annually. The prize carries with it a

Hi there, Suppose mu is constant, and error is normally distributed with mean 0 and fixed variance s. I need to find a statistics that: Y_i = mu + beta1* I1_i beta2*I2_i + beta3*I1_i*I2_i + +error, where I_i is 1 Y_i is from group A, and 0 if Y_i is from group B. It is large when beta1=beta2=0 It is small when beta1 and/or beta2 is not equal to 0 How can I find it by R? Thank you very much for your time. Fay

Hi all, I apologize for this off-topic question but I need your help -- I know there are lots of experts here. As a lover and student of statistics, I am thinking of building a tree of various branches of statistics and keeping track of the greatest historical inventions/discoveries in statistics and the latest development of each branch. The goal is to understand in what context did the great inventions come out and then try to follow the gre...

...="i", strata=rep(1,n), L=NULL, m=0, weights=NULL, ran.gen=function(d, p) d, mle=NULL, ...) When I create an object, containing the bootstrap statistic (object <- boot (....))I can call it and will get an output with t, bias and standarderror as follows: Bootstrap Statistics : original bias std. error t1* 5.65 0.01 0.9134185 My question is now, where is the value of the bias stored? How can I get access to this value to do further caluculations? Thanks, K. St.

Hi, Could anyone provide the formula of the statistics which the wilcox.test used for the two-sample rank-sum test? I got some statistics of 0 values, but it is impossible to have 0 "rank-sum". Does the function use the Mann-Whitney U test statistics? Thanks. Ting-Yuan Liu

Hi, there I am quite sure there is an easy answer to this, but I am unsure how to gather a bunch of t-statistics in an organized format. I am trying to generate a list of t-statistics for a randomization routine. If I try to collect a bunch of t-statistics from a run, this is what happens: > M <- 10 ; simt <- NULL > for(i in 1:M) + { + perm<-sample(site,replace=F) + + permute<-cb...

I am looking for online courses to learn Spatial Statistics using R. Statistics.com is offering an online course in December on the same topic but that schedule doesn't suit mine. Are there any other similar modes for learning spatial statistics using R??? Can someone please advice??? Thank you. Ravi -- View this message in context: http://r.789695....

I'm also having trouble installing R 1.3.1 on Solaris and getting png and jpeg support. It looks like perhaps the png and jpeg libraries I installed weren't built with all the support R needs. If that's the case I'd appreciate confirmation. Or perhaps there's something else I can do? (with all the details I've included this message is rather long) Thanks -Don I did

It looks like: multiEst<-function(dat,i) { .... c(E1,E2,E3,E2-E1,E3-E1,E3-E2); } then I call boot (using R=4 for simplicity of description) with: multiBoot=boot(data,multiEst,R=4) which gives reasonable results: Bootstrap Statistics : original bias std. error t1* 0.07 0.3775 0.04193249 t2* 0.08 0.3750 0.04654747 t3* 0.04 0.4200 0.05354126 t4* 0.01 -0.0025 0.00500000 t5* -0.03 0.0425 0.01500000 t6* -0.04 0.0450 0.01290994 and the resulting "t0" contains the expected estimates...

Can someone explain this difference, and especially why boot doesn't evaluate the frozen model again on the original data?
