Multigroup analysis in smartPLS again!

Post by Hosam »

Hi All,
I am conducting Multigroup analysis in pls path modeling using smartPLS.

I have male and female groups. Therefore, I splitted the data to run two measurement models separately followed by the structural models.

Bootstrapping was performed and I have slight differences in path coefficient between groups.

I followed Sarstedt, Henseler, & Ringle (2011) to test weather these differences are significant or not by performing " t statistic test " shown here

Sarstedt, Henseler, & Ringle (2011) posted in page 200 "The choice of test statistic depends on whether the parameter estimates’ standard deviations differ significantly across the groups"

My questions are:
1- Do the Parameters here refer to outer loadings only or something else?
2- They mention "Levene test" to check for invariance in Standard error while it is sensitive when data distribution is not normal. So how come?
3- am I following the correct procedures? please advice.

Thanks Julen, it seems the link you posted require more digging.

regarding the two equations, I noticed that the difference is very small. and mostly the assumption of unequal Standard error is active.

Unequal std errors assumed----------------Equal assumed
2.540*-------------------------------------------2.544*
0.3-----------------------------------------------0.299
1.264--------------------------------------------1.262
0.421--------------------------------------------0.429
1.72----------------------------------------------1.703
1.128--------------------------------------------1.156
0.853--------------------------------------------0.842
0.082--------------------------------------------0.084
0.47----------------------------------------------0.472
1.041--------------------------------------------1.066
1.2-----------------------------------------------1.194

Hi,

I want to conduct a multigroup analysis also, but not yet, I have to study more about PLS...

This might help also (point 3.5):

Hi,

If your group model invariance used Smith-Satterwaite Test for one solution.
