I have done an xtreg analysis and have presented the results - that is the value of Coef. ,Std. Err., z and P- in a table in a submitted paper. Reviewer now ask for more information about what coefficients Coef. and z refers to and what coefficient Std Err is referring to.
I have used xtreg to account for a possible cluster effect from seven centres participating in the study. Now reviewer wants me to inform more about how a possible cluster effect from the seven centres is tested by use of xtreg.
Can anybody help with one or two of these questions ?
