It is a bit easier to master than R and still cheaper than SAS. The OP did not indicate academic status, so just in case: Stata 8 SE current commercial single user license fees are $1,345 U.S. with full documentation and $1,215 U.S. with base documentation. Those are direct from the web site. > If the license fee is not an issue, I beleive that SAS is available for > Linux as well (although Alexander may be correct about the relative cost). A single processor "commercial" (as opposed to academic) use license for Linux for SAS is $7,800 U.S. for BASE and $4,200 U.S. for STAT. Those are the first year costs for the minimum two SAS components that would be required. Keep in mind that SAS is licensed on an annual basis. Subsequent annual renewals would be $2,560 U.S. for BASE and $1,390 U.S. for STAT. If you wanted SAS' GRAPH component, that would be $3,900 U.S. for the first year and $1,340 U.S. for subsequent renewals. A lot of people I know who use SAS for analysis use S-PLUS and/or R for graphics, simply because SAS GRAPH is a PITA to use. >> However the advice depends on what you need it for. >> Any package can produce simple summaries, graphs and the classical >> analyses.

I agree that one needs more information for a particular recommendation to be made here relative to functionality. For example, if one needs extensive exact methods, then StatXact (or the PROC STATXACT add-on module for SAS) would be the way to go. StatXact is not available on Linux however. Beyond the base R installation, which includes BTW, functionality for mixed effects models, there are ~500 add-on packages available to cover many expanded functions. Programming in R is a breeze as compared to programming in SAS, having been a SAS user for a number of years. If one needs to implement some new algorithm, there are interfaces for R to FORTRAN and C if needed and a large community available for help. That all being said, one needs to determine functionality requirements and budgets to aid in the decsion making process. HTH, Marc Schwartz
