Detect duplicate observations in a data set in Stata. You can check for duplicate observations in Stata in the following ways: The isid command can detect duplicate observations: . isid x1 x2 x3; The duplicates command can list and flag duplicate observations. The list subcommand lists the duplicate observations: . duplicates list x1 x2 x3

I dag är upphovsrätten framförallt utmanad av den tekniska utvecklingen, och det krävs att vi tar tag i frågorna innan lagstiftningen är föråldrad, 

When it comes to exporting regression tables from Stata to LaTeX, there are several packages that can be used. For a long time, I used outreg2, but now improved my code for the the estout package by Ben Jann. Let's say I have the following data: id disease 1 0 1 1 1 0 2 0 2 1 3 0 4 0 4 0 I would like to remove the duplicate observations in Stata. For example id disease 1 1 2 207.7k Followers, 444 Following, 1,977 Posts - See Instagram photos and videos from ALBERTINO (@albertinodj) See help egen and look for the functions that start with row : rowmean(), rowmin() , rowmax(), rowsd(), rowtotal(), etc. tag() and group() These two function are really   Downloadable!

tag variable and then look at observations with tag not equal to 1 because both unique observations and groups with two or more surplus copies need inspection.. duplicates tag, gen(tag) Duplicates in terms of all variables As of Stata 11, the browse subcommand is no longer available. To open duplicates in the Data Browser, use the following egen tag_emrvendor=tag(hospitalid emrvendor) bysort hospitalid: egen n_vendors=total(tag_vendor) But I can't make the frequency table which shows the number of vendors used per hospital 2) EMR functions that a different emrvendor is used per hospital Stata: Generate new variable with all values (e.g. not just max or min) for a group based on other variable in the group 1 How to see if all values within group are unique/identify those that aren't Stata’s official commands do not give much support to multiple response variables, although we gave an example earlier of the application of tabstat. One general strategy is to use an egen function to calculate something, (possibly) egen, tag() to tag just one observation in each of several groups, and then list to show egen— Extensions to generate 3 max(exp) (allows by varlist:) creates a constant (within varlist) containing the maximum value of exp. mdev(exp) (allows by varlist:) (Stata interprets _N to mean the total number of observations in the by-group and _n to be the observation number within the by-group.) Having created the new variable dup, you could then .

Introduction 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. Let’s see how _n and _N work.
