**create dummy – convert continuous variable into (binary**

Ways to count the number of unique values in a variable. the number of rows in the table, that is, the number of unique observations for variable varname. The problem with using -tab- to count the unique number of values is its row limits: 12,000 rows (Stata/MP and Stata/SE), 3,000 rows (Stata/IC), or 500 rows (Small Stata). inspect varlist display r(N_unique) Besides reporting the number...

**Recent Advances in the Field of Trade Theory and Policy**

In the xi command, the prefix(i)option gets rid of Stata's default prefix, "_I", which it adds to each dummy variable name. We use the noomit option because xi does not create a dummy for the lowest value (remember, it's designed to feed these dummies into a multivariate procedure, so one … how to close mason jar lids String to append DataFrame column names. Pass a list with length equal to the number of columns when calling get_dummies on a DataFrame. Alternatively, prefix can be a dictionary mapping column names to prefixes.

**Seasonal Dummy Model SSCC**

Here is a flexible solution using PROC FREQ and PROC TRANSPOSE. The SPARSE option gets you your zeros. I assume you only want 1 or 0, hence the NODUPKEY sort; remove NODUPKEY (or remove the sort entirely) if you do want 2 for BREAD for the first ID. how to create hanging indent for apa references In the xi command, the prefix(i)option gets rid of Stata's default prefix, "_I", which it adds to each dummy variable name.
