Webis to use Stata’s factor-variable notation (see [U] 11.4.3 Factor variables). In that case, the default is to leave one category out, the so-called reference category. However, the factor-variable notation also allows you to include an indicator variable for the reference category. This can provide a useful alternative representation of the ...

WebStata will assume that the variables on both sides of the # operator are categorical and will compute interaction terms accordingly. • Hence, we use the c. notation to override the default and tell Stata that age is a continuous variable. • So, c.age#c.age tells Stata to include age^2 in the model; we do not WebOct 19, 2012 · Introduction to factor variables in Stata®, part 3: More interactions 19,321 views Oct 19, 2012 Explore how to use factor variables in Stata to estimate interactions between a categorical... WebJan 21, 2013 · Basically, the idea is that you run any regression using Stata's factor variable notation, where you tell Stata that a variable X is continous and should be interacted with itself, eg reg y c.x##c.x is the notation to regress Y on X and X^2.
