This question already has an answer here:

I am using a Poisson regression model with a count data. More specifically, my dependent variable is the number of children dead.

My feeling is that I could use a Poisson model with an offset variable containing the number of children ever born.

However, I would like to know if I can just use the number of children ever born as an explanatory variable as it will control for these effects. Or rather, instead of to use the number of children ever born as an offset variable, just use it as a control variable.

Anyone can help me?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • $\begingroup$ What do you mean: ever born? since time immemorial? I would guess total number of children born in the same birth cohort as the dead children are from (log of that as an offset, yes .)
