First, let me say that I think it's really admirable–and pretty cool–that you the SWIID, 1960 to the present (with apologies for the raw Stata output).

This module will show how to create labels for your data. Stata allows you to label your data file (data label), to label the variables within your data file (variable labels), and to label the values for your variables (value labels).). Let’s use a file called autolab that does not have any labels. Posts about keeping the first observation written by pureumkim. Skip to content. Search for: Search.

The variable names in Stata can't start with a number, so, if the first row of observations contains only numbers (e.g., years), one must add a prefix to the new names. For example, for "year" it'd look like this:

Stata: Keeping the first or last observation in a group. November 24, Posts about first and last observation 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. For subject id =1, all of her values are duplicated except for her math score; one duplicate score is set to 84.

_N counts the total number of observations.
