## Examples

### Graphing the Regression Line

One of the most common graphs people want to make is to add the regression line
to a scatter plot of the data. This example shows how you can easily do this in Stata.

### Interaction Terms

This example considers interactions between independent variables
in cross tabs and regressions.

### Modelling Binary Dependent Variables

What do you do if your dependent variable is binary? For example, what if we want to
model the effect of the age of the respondent on whether or not the household owns a
TV. This example goes through three different ways to do this (linear probability, logit
and probit) and compares and graphs the different models.

### Fixed Effects

There are multiple ways of implementing a fixed effects regression in Stata -- make your own dummy variables,
use the prefix

xi, use the commands

areg or

xtreg,
or employ techniques such as demeaning or first differences.
This example goes through these different
ways and discusses the advantages and disadvantages of each.
