Interaction In Stata. Each coefficient is interpreted as. It means that the slope of the continuous variable is different for one or more levels of the categorical variable.
Y b 0 b 1 x b 2 w b 3 x w. Interactions are formed by the product of any two variables. Each coefficient is interpreted as.
The most intuitive way to do so is to generate the interaction term as a new variable.
Stata 12 introduces many new commands. But of course we cannot cover every possible method that is included in the contrast command. We will use an example from the hsbdemo dataset that has a statistically significant categorical by continuous interaction to illustrate one possible explanatory approach. Each coefficient is interpreted as.
