Singular Matrix Error in 2nd order

Post by Omayusuf » Tue Jun 23, 2020 9:49 am

Hi,
I am having difficulty running bootstrapping on the attached model. It keeps returning the error message "Singular Matrix" Problem. Can somebody please help me out on this?

You build a model that suffers from perfect multicollinearity. Your construct Tax_Inc is a combination of for constructs. You cannot put all four constructs as well the their combination at the same time in a regression on a final construct.

Dear Prof

I was wondering if you could let us know why we cannot put all four constructs at the same time in a regression on a final construct. Please

Thank you very much in advance.
