Hi User's, This might be a simple question but it is giving me a hard time as I am a new user. I installed R version 2.9.2 (2009-08-24) 1. I just copied a short script from Fox (2002) as a practice and wanted to save it as Rossi.R. The system saved it without complain but when I looked at using a windows explorer it is not *.R file but only Rossi. Why this is happening? 2. the script and the data files are in the same working directory. When I run the following script > Rossi <- read.table('Rossi',he...

Dear Germano, Thank you for your fast reply, In the above code, *MYData *is the actual data set.

Hi R-users, I have the following problem: I am trying to learn something about bayes methodology and started paying around bayesm package, but could not replicate the Conjunctive model's estimates as they appear in Rossi et al "Bayesian Statistics and Marketing", 2005, JWS, pages 264-265, Table CS4.4. I have downloaded in my working directory the documents from http://faculty.chicagobooth.edu/peter.rossi/research/bsm.html and then i have sourced the functions 2 times: one with 1000 MCMC iterations (i si...

...using MCMC simulation methods, it takes about 20 minutes to run the complete set of examples on a 2.8 Ghz windows PC. The R process reaches a high water mark of about 100 MB of memory as well. I would appreciate some guidance on this. many thanks! peter ................................ Peter E.

...w a package (similar to MASS) or a function (similar to fitdistr) I can use to estimate the parameter of these distributions using MLE method? Otherwise do you know a function (which use MLE method to estimate distribution parameters) that allow me to specify a PDF or PMF?

...C or Fortran. I've installed Rtools, Perl, the MS hhc, and so on. I am setting up a command shell with the correct PATH for building packages. (The master Windows PATH points to different versions of make and grep that I prefer for my usual work.) Two questions: 1. GUIDANCE. Is the Peter Rossi document now the best place to look for detailed guidance? I have located it at http://www1.appstate.edu/~arnholta/Software/MakingPackagesUnderWindows.pdf The links to it on the R Project Website are no longer good.

For instance try: pmixedgamma3(c(10,20),shape1=10,rate1=1,shape2=10,rate2=1,prev=0.5) As you can see cumdensity is calculated just for the first x value.
