Furthermore, what does _n mean in Stata?Stata has two built-in variables called _n and _N. _n is Stata notation for the current observation number. _n is 1 in the first observation, 2 in the second, 3 in the third, and so on. _N is Stata notation for the total number of observations.Additionally, what is the Egen command in Stata? The Stata command egen, which stands for extended generation, is used to create variables that require some additional function in order to be generated. Examples of these function include taking the mean, discretizing a continuous variable, and counting how many from a set of variables have missing values. Subsequently, question is, what is Stata Varlist? A varlist is a list of variables, and Stata provides various shorthand conventions to avoid typing out long lists of variables. An asterix (*) represents any number of characters and is used in varlists that expand to all variables that match.What is a distinct variable?Observations are distinct on a variable list if they differ with respect to that variable list. Unique observations are also often interpreted to mean those that occur precisely once in the data.
