-gsort-, on the other hand, can sort the observations in either ascending or descending order. There are two commands in Stata that can be used to take a random sample of your data set. Use the sample command to draw a sample without replacement, meaning that once an observation (i.e., case, element) has been selected into the sample, it is not available to be selected into the sample again. I have tagged the number of occurrences of each unique anonymised id (ida) by date using the code below to give me scan number (snum). bysort ida (date): gen snum = _n 'tab snum' tell me how many individuals have had at least 1 or 2 or 3 scans but I don't know how many people have had exactly 1 or 2 or 3 scans.

Stata tag unique

The variable hhid has 60 unique values and if I understand the data correctly, this means there are 100 observations from 60 households. Last edited by Friedrich Huebler ; 12 Sep 2017, 19:39 . Comment In the dataset, the variable id is the unique case identifier. To add the duplicate observations, we sort the data by id, then duplicate the first five observations (id = 1 to 5). This leads to 195 unique and 5 duplicated observations in the dataset.

_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.

Combine text, graphs & statistical analysis Example: I usually export regression tables from Stata in file format .tex, and Thus, if values of a variable are 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, and 5, then in one sense of “unique”, there are five distinct or unique values—namely, 1, 2, 3, 4, and 5—whereas in another sense there is just one unique value—namely, 1, the only value that occurs precisely once. The variable hhid has 60 unique values and if I understand the data correctly, this means there are 100 observations from 60 households. Last edited by Friedrich Huebler ; 12 Sep 2017, 19:39 .

Comment In the dataset, the variable id is the unique case identifier. To add the duplicate observations, we sort the data by id, then duplicate the first five observations (id = 1 to 5). This leads to 195 unique and 5 duplicated observations in the dataset. Thus unique observations are tagged with value 0, and all duplicate observations are tagged with values greater than 0. For checking double data entry, in which you expect just one surplus copy for each individual record, you can generate a tag variable and then look at observations with tag not equal to 1 because both unique observations Stata: Generate new variable with all values (e.g.
