To assign the values of one variable as the value labels for another variable, you can use the “label define” command in a statistical software program. This command allows you to create a set of value labels for a variable, and then assign those labels to another variable by specifying the variable and the corresponding label values. This process can be useful for organizing and interpreting data, particularly when dealing with categorical variables. By assigning value labels, you can easily identify and analyze the different categories represented in your data.
How do I assign the values of one variable as the value labels for another
variable? | Stata FAQ
Sometimes two variables in a dataset may convey the same
information, except one is a numeric variable and the other one is a string
variable. For example, in the data set below, we have a numeric variable
a coded 1/0 for gender and a string variable b also for gender but
with more explicit information. It is easy to use the numeric variable, but we
may also want to keep the
information given from the string variable. This is a case where we want to
create value labels for the numeric variable based on the string variable. In
Stata, we can use the command called labmask to create value labels for
the numeric variable based on the character variable. The command labmask
is one of the commands in a suite called labutil written by Nicholas J. Cox. You can download it by
typing search labutil (see How can I
use the search command to search for programs and get additional help? for
more information about using search) and then following the link to it.
Example 1: A simple example
clear input gender str8 female 1 female 0 male end list+-----------------+ | gender female | |-----------------| 1. | 1 female | 2. | 0 male | +-----------------+ labmask gender, values(female) describe Contains data obs: 2 vars: 2 size: 32 (99.9% of memory free) ------------------------------------------------------------------------------- storage display value variable name type format label variable label ------------------------------------------------------------------------------- gender float %9.0g gender female str8 %9s ------------------------------------------------------------------------------- Sorted by: Note: dataset has changed since last saved list +-----------------+ | gender female | |-----------------| 1. | female female | 2. | male male | +-----------------+ label list gender: 0 male 1 female
Example 2: Another example
How is labmask different from encode? Both of the commands
create value labels for the numeric version of the string variable. However, the command
encode does it based on the alphabetical order of the string values, not based
on the values of the numeric variable in the data set that we want to match it
to. For example, the new variable cnum below created by encode will
have value 1 for boston since it the first alphabetically.
clear
input cityn str8 cityc
0 la
0 la
2 boston
2 boston
5 chicago
5 chicago
5 chicago
3 ny
3 ny
end
encode cityc, gen(cnum)
labmask cityn, values(cityc)
