  • Logistics regression

    Dear all,

    I am running a logistics regression to for example investigate whether the gender of the children living in the same household is associated with their nutritional divergent.

    I use the command below;
    logistic divergent_nut_outcome i.gender


    [CODE]
    * Example generated by -dataex-. For more info, type help dataex
    clear
    input str3 uid byte age_months long(gender nutritional_status) float divergent_nut_outcome
    "119" 52 2 1 1
    "119" 21 1 2 1
    "119" 5 1 1 1
    "131" 40 1 1 1
    "131" 5 2 2 1
    "311" 54 2 1 1
    "311" 11 2 2 1
    "419" 39 1 1 0
    "419" 59 2 1 0
    "419" 19 1 1 0
    "525" 33 2 2 1
    "525" 21 2 1 1
    "526" 57 1 1 0
    "526" 8 1 1 0
    "633" 39 1 1 0
    "633" 34 1 1 0
    "7 2" 27 2 2 0
    "7 2" 7 2 2 0
    end
    label values gender gender
    label def gender 1 "female", modify
    label def gender 2 "male", modify
    label values nutritional_status nutritional_status
    label def nutritional_status 1 "Normal", modify
    label def nutritional_status 2 "Undernutrition", modify


    Am I correct?

    Alternatively, I also taught of collapsing the divergent_nut_outcome by household' before I run the logistic regression,
    However, if I do so, I will face with potential bias when collapsing the data to a single observation per household and the risk of losing individual-level information like sex, age.

    What is the best way to go?

    Thank you.
    I do appreciate your time and support.
