Hello All,
I am running a quantile regression on log of wage as my dependent variable with other explanatory variables which also include an interaction term. I ran the regression on stata 12 which gave an error message "interactions not allowed". My interacting variables comprises a categorical and contineous variable. Please find the generated command as follows:
xi: sqreg lwage i.MARR one_child two_children three_children more_than3_chil i.MARR#c.child hhsize exper exper2 i.educ_levels i.zone i.Secto i.isco i.Asset i.Urban if gender==1 & Wage_self_emp==2, q(.25 .5 .75)
i.MARR _IMARR_1-3 (naturally coded; _IMARR_1 omitted)
interactions not allowed
r(101);
Also, the interaction variables are Marrital status and no. of children: See table below
tab MARR
MARR | Freq. Percent Cum.
------------+-----------------------------------
Other Union | 790 5.57 5.57
Married | 7,529 53.09 58.66
Single | 5,862 41.34 100.00
------------+-----------------------------------
Total | 14,181 100.00
The children variable:

2 | 2,227 19.74 41.50

6 | 705 6.25 93.17
7 | 380 3.37 96.53
8 | 201 1.78 98.32
9 | 97 0.86 99.18
10 | 39 0.35 99.52
11 | 14 0.12 99.65
12 | 15 0.13 99.78
13 | 12 0.11 99.88
14 | 5 0.04 99.93
15 | 8 0.07 100.00
------------+-----------------------------------
Total | 11,283 100.00
I would appreciate any help and commands that I can apply to run a quantile regression on these variables including the interaction terms.
Looking forward to your contribution.
