  • POISSON and IRR

    Hello guys,
    I have some questions on Poisson regression.

    1- I have continuous and categorical variables; the outcome is the number of children. I was confused about how can I interpret the continuous variables. Can I use this formula [ exp(b1)-1]*100) from Wooldridge's book to interpert continuous variables or the formula only for categorical variables.

    2- Is it a good idea to gather Coef. and IRR in one table?

    3- What is the command for extracting the table of IRR to the word doc? I sued
    [poisson N_CHILDREN HOUSHOLD_INCOME FEMALE_SHARE_EARNING i.EDUCATION i.AGE i.MARITAL_STATUS i.RACE i.HISPANIC, irr
    outreg2 using P_2016.doc, replace ctitle(Model 1)]

    Hm:
    1) the formula you mentioned is useful when you calculate the marginal effect on the regressand of a regressor (when adjusted for the other eones) in log-linear regression, where the regresand is continuous, though;
    2) it depends on what you're interested in disseminating;
    3) the new -table- suite can be helpful in this respect.
    Kind regards,
    Carlo
