I saw an ad in the July 2001 Amstat News for a complex sample survey analysis package called Wesvar. The package has what appears to be a useful feature called a "Workbook" by which the user navigates analysis output. This is a hierarchical tree in which the user may click on a part of the analysis (table, regression fit,...

Do you know of any references that verify the accuracy of R for basic statistical calculations and tests. The results of these studies should indicate that R results are the same as the results of other statistical packages to a certain number of decimal places on some benchmark calculations. Thanks, Corey Powell Clinical Data Analyst Broncus Technologies cpowell@broncus.com [[alternative

Hi people, I need to prove the good quality of numerical accuracy of R. Anyone knows a paper or anything else comparing R to other statistical softwares in terms of numerical accuracy. I've made a long search about that but I found nothing. Please help me!! Thanx, Talita Leite ------------------------------------------------- Este e-mail foi enviado pelo Webmail da UFAL IMP:

Hi the list, I use rgl to produce a 3D graph. I would like to "show" this graph to some collaborator. Is there a way to save it and send it to someone else? Christophe Genolini

It was a note on an earlier article by Cureton, who in turn cited an American Journal of Psychology article by Holtxman(1950, v63, 615-617). http://amstat.tandfonline.com/doi/abs/10.1080/00031305.1968.10480435?src=recsys Searching on that article I see the first hit is a citation to some R documentation for hte MBESS::s.u function, which does implement it as recommended by Holtzman. If I were voting on this I would put greater weight on the JK&...

Hi, I am using "line" function to plot the line. And I would like to understand "Tukeyline" algorithm. Since, the line function is calling the Tukeyline algorithm(which is compiled code) using foreign function interface, I am not able to look into the source code of this algorithm. Can somebody help me out, so that I can refer the same. Thanks in advance!!! Thanks,

Dear List Members, I am in the process of designing a study examining pay and performance in Major League Baseball across several seasons, and before I get too deeply into it, I'd like to ask whether the group members think that performance across seasons is independent, or if it needs to be treated like a time-series variable so that lack of independence can be controlled. Any ideas or
