I ran this equation on Stata:
Y = b0i.EMPLOYED + b1i.FEMALE + b3c.EDU_YEARS +
probit ownland b4(i.EMPLOYED##iemployed##i.FEMALE##cfemale##c.EDU_YEARS)eduyrs
where EMPLOYED =ownland is =1 if the respondent owns agricultural land; employed= 1 if the respondent is currently working, FEMALE =female= 1 if the respondent is a woman, and EDU_YEARS captures years of education.
b0 would be the effect of being employed on Y for uneducated men b1 would be the effect of being a female on Y for unemployed and uneducated women, compared to men. b3 would be the effect of years of education for unemployed menThe results I receive is

How would you interpret b4? Would it beI am pretty clear on the effectinterpretation of being employed women"employed", "female", and "eduyrs" on Y for a unit change in years of education?the outcome:
- Employed variable would be the effect of being employed on Y (ownland) for uneducated men
- Female variable would be the effect of being a female on Y for unemployed and uneducated women, compared to men.
- eduyrs variable would be the effect of years of education for unemployed men
How canBut I obtainam confused about the net effect of an increase in yearinterpretation of education for employed female versus unemployed female? Would that be (b0+b2+b3+b4)-(b1+b3) = b0+b2?other variables.
- How would you interpret the estimated coefficient for Employed#Female#c.eduyrs? Would it be the effect of being employed women on Y for a unit change in years of education?
- How can I obtain the net effect of an increase in year of education for employed female versus unemployed male? Would that be nlcom (employed+ female+ i.employed#i.female+eduyrs + Employed#Female#c.eduyrs)-(eduyrs)?
- How can I obtain the net effect of an increase in year of education
for employed female versus unemployed female? Would that be
(employed+ female+ i.employed#i.female+eduyrs + Employed#Female#c.eduyrs)-(female + eduyrs + female#eduyrs)?
If someone could enlighten me on this, that would be very helpful. Thank you so much!
