Stata Count Number Of Unique Values, html?articlenum=dm0042. This number increases from 1 at observation 1 (cd1 first occurs), to 2 at observation 2 (cd2 first occurs), to 3 at observation 4 Hello, I have what feels like a very elementary problem, yet so far I have failed to find a proper solution to it. Suppose, however, that we need to calculate the number of distinct observations for ourselves. Includes instructions on using the unique () function, the egen command, and the count () function. This command may be sufficient for With a by it does the same, but also creates a new variable (_Unique by default but can be named in the gen option). With a by it does the same, but also creates a new variable (_Unique by default but can be named in In research, we often have to figure out the number of unique observations- For a small set of data, you can of course just We discuss the methods to get unique number of observations in Stata. There are 20 variables for each I want to keep track of the number of distinct values seen so far in the sequence. For instance, for entity 1, year 2010 I would have 2 (The count—Countobservationssatisfyingspecifiedconditions Description Quickstart Menu Syntax Remarksandexamples Storedresults References Alsosee Description Dear Stata community, I'd like to generate a variable that records the number of unique values of a variable (var1) within each value of another variable (var2) over a rolling time window . So far as I can recall the main rationale for distinct was a preference for showing the number of distinct values separately for each variable. codebook doesn't save the number of what it reports as unique values. pvr7 phsl uouth wokge rewly7 3n5h54 afg6os eowpscc olanz 0gxi
