Difference in results between SPSS and SmartPLS

Post by bubach »

Hello all,

I calculated the cronbachs a in SPSS and SmarPLS and i found a slight difference. I guess this is caused by rounding errors.

I also did a simple regression in SPSS and the same in SmartPLS. I found significant different between R-square and the path-coefficients.
Could anybody explain why?

Thanks you very much!

Hi,

minor differences are caused by rounding indifferences in different software applications.

However, the regression results in SPSS, R and SmartPLS are identical. You probably used a linear regression with constant term in your analyses.
