you are right about the 3rd line but it doesn't help me for my problem. I
remove the 3rd line but there is still the same problem:

Might have just solved my own problem team!
I assumed that the issue here was the replicated samples, and so added a

R seemed to like this and was happy to run the test!

Hi,
I can think of no reason a Hausman test could not be used for OLS---it is a
comparison of vectors of coefficients from different models usually assumed
to produce similar estimates under certain conditions. Dissimilarity is
taken as indicative of a lack of some or all the conditions required

I am really new to statistics in R and statistics itself as well.
