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. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding at nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 167 1972 Date: 21-Feb-04 Time: 12:54:13 ------------------------------ XFMail ------------------------------
