st: interpreting probit coefficient |

Hi Stata list I kindly need help with interpreting coefficients from a probit regression. I have a dataset and I want to examine how years of marriage, polygamy, dowry payment predict probability of domestic disputes among married couples in a country. I have run the command below probit m181_dispute m3_yea m7a m11a, r I followed that with margin, dy/dx(*) my variable names are m181_dispute = 1 if there was a domestic dispute, 0 if otherwise m3_yea = length of marriage in years m7a = 1 if husband has more than 1 wife, 0 if has 1 wife m11a = 1 if husband has paid dowry, 0 if not After I run the margin command, I get dy/dx m3_yea | .0050716 m7a | .021586 m11a | -.0608191 m12a | -.0176505 I understand that, because m3_yea is a continuous variable, it would be accurate to interpret the marigin coefficient on m3_yea as 1 additional year of marriage would on average decrease probability of occurrence of domestic disputes by 0.5 percent. I am, however, confused as to how to interpret a margin coefficient on an indicator variable. For instance, I was wondering whether it would be accurate to interpret the margin coefficient on m7a as the probability of domestic disputes occurrence in marriages with more than 1 wife is on average higher by 2.16 percent than in those with one 1 wife.
