Controlling independent variables in multinomial logistic regression

[Rodrigo Retamal]

Hi,

I am analysing the effect of sex, age (categorical), and education level (categorical) over the Covid-19 social impact (categorical variables, 3 categories). How can I control the effect of sex and age before introducing the education variable?

help nestreg

Example:

// -mlogit- example from the help file
// Setup
webuse sysdsn1, clear
// Fit multinomial logistic regression model
mlogit insure age male nonwhite i.site
// Suppose I want to enter site, age and male first,
// and then add nonwhite on a second step.
// Use the -nestreg- prefix command (help nestreg)
nestreg: mlogit insure (i.site age male) (nonwhite)
