Stata Tutorials Topic 39: Marginal Effects | Regression Analysis and Estimation Methods Using Stata

Hi, I am Bob. Welcome to the Stata course on regression analysis and estimation methods. In the last topic, we use the "margins" command to obtain the log hourly wage predictions at different explanatory variable values. We draw graphs to show how the average hourly wage changes with the explanatory variables using the "marginsplot" command. We used the margins and marginsplot commands to compute the predictions of the outcome variable and draw curves of the predictions against some explanatory variables. In addition to computing predictions, the margins and marginsplot commands are very useful in calculating the marginal effects of the explanatory variables. In this video, we will closely examine the "margins" command and produce the marginal effect of the explanatory variable on the outcome variable by using the "dydx" option. The marginal effect is also called the partial effect because we hold the other variables fixed.

The Stata commands in this video:
*Marginal Effect of Schooling on Wage
regress lwage schooling age i.married i.female

margins, dydx(schooling)

*Marginal Effect Differs between Gender Groups
regress lwage c.schooling##i.female age i.married

margins, dydx(schooling) at(female==(0 1))

marginsplot

*Marginal Effect Changes with Schooling itself
regress lwage c.schooling##c.schooling i.female age i.married

margins, dydx(schooling) at(schooling==(6(1)17))

marginsplot

*Other Examples
regress lwage c.schooling##c.age i.married i.female

margins, dydx(schooling) at(age==(25(5)54))

marginsplot


regress lwage c.age##i.female schooling i.married

margins, dydx(female) at(age==(25(5)54))
