[R-sig-ME] What p value should I report here?

[DESPINA MICHAILIDOU]

Hi everyone,


I am running this regression analysis model and I get the following output.
What P value should I report for my variable P-Dizz today?What does it mean
that fixed-effect model matrix is rank deficient so dropping 1 column /
coefficient? Can anyone help me with the interpretation of those data?


Thank you in advance.
