SOCY401- Introduction to margins & marginsplot in Stata

This short video shows you how to 1) estimate a bivariate regression model, 2) produce predicted values,  & 3) visualize the model.

Stata Code
/*
  Stata help using the margins command
    Uses the GSS data
*/

/* Create a subset of the GSS data */
keep year realrinc educ
drop if educ LT 8     /* Youtube does not allow using the less than symbol.  Stata requires it */
keep if year==2018
drop year
keep if !missing(realrinc, educ)


/* Estimate a model of the relationship between income & education     */
regress realrinc educ                  /* Estimate a model             */
display -25386.6 + 3543.642*12         /* Calculate Y-hat for educ=12) */

/* Calculate predicted values */

summarize yhat if educ==12

/* Use margins to calculate the predicted values */
