Linear regression model

By SharonYu | Mar 01, 2018 04:38AM CET

I am an xlstat user, I just tried to run a very simple multiple linear regression model, the model has just linear terms of first order with the format like: y~x1+x2+x3+x4+x5+x6+x7+...+x15 (with intercept), while the output coefficient estimations are different from what I got from either R or SAS, the outputs from R and SAS are the same. So I am confused of whose results should I trust. If possible, can i know the root cause of the discrepancy? Thank you!

Hi Sharon,

Options sometimes differ from one software to another, so if your model’s configuration is not exactly the same between XLSTAT and R then this might cause different results.
You can send us your XLSTAT results at support@xlstat.com and we will validate these for you.
