R/SigmaStat

Hi Folks,

I have run a linear regression analysis in R on some data for which
I also have a printout of a similar analysis carried out by someone else.

The results (intercept, coefficient, SEs etc.) differ somewhat, though
not greatly.

From the printout of the other analysis, it seems that it may have

been produced by software called SigmaStat.

(I'm going by the clue

 "Power of performed test with alpha = 0.0500: 1.000"

 in the printout, which on a google search throws up a lot of SigmaStat
 and sometimes SigmaPlot; the web pages illustrate tabulations by
 SigmaStat which are very similar in layout to the printout I have)

I'm not familiar with SigmaStat. I'm a bit concerned by the numerical
discrepancies (and somewhat puzzled by the "1.000" power against an
unstated alternative!).

If any of you have experience with SigmaStat, especially in comparison
with R, I would be interested in your comments. If you would prefer to
email me off-list, please feel free to do so!

Best wishes to all,
Ted.
