Dear all,

I am using Stata 16, on mac. Here is the code that I have:

asdoc reg hard_drugs_DLI ait Dit fp1 hard_drug_start enl_mil employed_01_int employed_02_int employed_03_int employed_04_int employed_05_int employed_06_int employed_07_int employed_08_int employed_09_int mil_01_employer mil_02_employer mil_03_employer mil_04_employer mil_05_employer mil_06_employer mil_07_employer mil_08_employer mil_09_employer college_enroll i.year, vce(cluster PUBID_1997) add(cluster id, Y, Year Effects, Y, birthday Xi Xit fixed effects, YNYY) fs(6) drop(i.year fp1 enl_mil employed_01_int employed_02_int employed_03_int employed_04_int employed_05_int employed_06_int employed_07_int employed_08_int employed_09_int mil_01_employer mil_02_employer mil_03_employer mil_04_employer mil_05_employer mil_06_employer mil_07_employer mil_08_employer mil_09_employer fp2 fp3 hard_drug_start sex race int_bday college_enroll ait Dit) dec(3) cnames(Model 1) row nest save(Regression) append

Is there a way I could add fixed effects to this code?

Thank you so much in advance,
