MGA -Singular Matrix error
Posted: Mon Jun 04, 2018 2:33 am
Hi.
I have 8 latent variables and 8 control variables.
In terms of the control variables, I have 4 categorical variables including gender, chatting experience, etc.
So I transformed these to dummy variables.
In result, 4 dummies ware made.
When I used standard bootstrapping(5000 times), I can get t statistics and p values.
But, when I used MGA to examine how the path coefficients are different between two groups(having chatting experience vs not having chatting experience), singular matrix error occurred.
How it can be possible?
In my humble opinion, because the standard bootstrapping was ok, both my dummies and data are ok as well.
greetings
