I've got no problems, generally with excel. Just don't make me use it, since there is no reasonable way to provide an audit trail of what was done. However, part of the reason for suggesting the two packages is that they CAN use excel files. Note that I've just suggested 2 cross-platform, freely available alternatives. There is no reason NOT to have access to either product in the workplace (since both will work on macs, windows, (and while vista's support isn't as good here) unix). So now, the question becomes, why bother with minitab, since you could provide training on software that they can have available (Excel, and R or ViSta). best, -tony -- A.J. RossiniRsrch. Asst.

Spreadsheets do form a nice means for thinking about datasets. In fact, a good number of "decent" statistical packages can interact with spreadsheets, or provide a spreadsheet-style interface. There are a number of rather useful EDA tools that spreadsheets like Excel provide (easily programmable in R or XLispStat, to name my two favorite statistics languages). So, what's missing in spreadsheets? the ability to designate dataset structures for statistical modeling with the same flexibility as a decent statistical language (I'm thinking generalized linear models (not general linear models!), correlated regression, event-time regression analysis; robust numerical computations at the same level, and a large set of tools. However, more critical is, "what's missing in statistical languages?", and I think that the answer are tools to help novices ramp up "properly". I'll leave the definition of "properly" open for debate. -- A.J. RossiniRsrch. Asst.

Dick Depends on which definition of "biometry" you are using. One definition used to be an older name for what is now biostatistics (and what might again become biometry, according to how some in the field want to rename it again to make it more relevant to measurement and design). That's a nice murky response, which shows how our language is ill-defined. There are other definitions, which have little to do with statistics. best, -tony -- A.J. RossiniRsrch. Asst.

BW> There was a thread on "biostatistics versus statistics" a BW> couple years ago, I think, but I was unable to find it at BW> google groups. Maybe someone out there saved some of it. But it's much easier than that. Biostatistics is simply statistics (design, descriptive, and inferential) applied to medical, basic biology, and public health problems. So while a decent biostatistician need only concern themselves with knowing all of statistics (which of course requires knowledge of most of computer science and mathematics), as well as one or two of the above scientific areas, a truly good one will know most science and study related to medicine (which of course should include biochemistry, economics, clinical trials, etc). I'm only being slightly facetious. I've come across the need to know parts of nearly all of the areas mentioned above in my work, both to communicate with as well as handle data analyses appropriately for clients and colleagues. best, -tony -- A.J.
