# Different results for linear regression in SPSS vs JASP

Hi all,

Are you familiar with the fact that spss gives different results for regression than regression in JASP?

I did Bayes regression and found good results, and when checking with 'normal' regression in JASP I found similar results. However, the same analysis in SPSS resulted in non-sign findings and no correlation. The opposite of what was found using JASP.

Do you have an explanation? Of course I hope JASP outcomes are correct

Thanks!

Hi Sanne,

We use code from R packages, and most of the time SPSS is wrong and R is right, but who knows, this may be an exception. Can you provide more specifics so we can look into it?

Cheers,

Hi E.J. and Sanne,

I have encountered the same discrepancy (example below).

JASP does indeed provide the same answer as R but it's different from SPSS and I was wondering why? Given that the differences are quite substantial.

Thank you in advance for any advice.

In JASP:

Same as R

In SPPS (sorry for the formating):

I am not sure what outputs to compare, exactly, but I googled this problem and it has been noted a few times before. From what I see, most of the time the issue is rounding (!). For instance see https://stats.stackexchange.com/questions/113314/spss-and-stata-output-different

It's great that you've also posted this issue on our GitHub page. We might take a while to get to this, but we will at some point.

Susanne, on GitHub you said that you resolved the issue. What was the cause of the discrepancy?

Cheers,
