My research topic is about child mortality and risk factors, including education, age, child with full vaccination or not and so on.
so my outcome is child mortality, where 0 means alive and 1 means death.
All risk factors (variables) are dummy variables.
My problem is that i tried to do logistic regression as below:
logit child_mortality ib1.gender ib1.wealth ib1.ch_fullvaccine, or
but the results showed outcome does not vary.
To figure out, i tried to do single regression first:
logit child_mortality ib1.gender,or
All results are fine except the variable ch_fullvaccine. the results indicated outcome does not vary.
May i know how to deal with it?
