Modifying existing value labelsР В РІР‚СњР вЂ™Р’В®xisting labels can be modified with the help of options. As of Stata version 12, value labels are also shown in the 'Variables' section of the Properties window. If you don't remember name of the label attached to a variable, you can find it with the help of the describe or the codebook command (just insert the variable name after the respective command). Note that 'mstatus' is the name of the label, not of the variable. Will display a table showing the correspondence between values and labels of the variable 'mstatus' labelbook will present some additional information and will underline the first 12 characters of each label which helps you to judge whether the labels will be unique in a typical piece of Stata output. Information about value labels that exist in your dataset I advise my students to create labels that convey significant information with the first 8 characters or so, otherwise labels may become indistinguishable in the output of some procedures. Label define can be abbreviated as la de and label value as la val.Р В РІР‚СњР вЂ™Р’В¬hoice of value labels is not easy, as often only a small number of characters will be displayed. You still will define one label as in the example above and attach it to variables, say, status1 to status 10: To return to our example, there may be a list of up to 10 household members, and for each member there is a variable indicating whether s/he is married or not. The advantage of this two-step procedure is that often several variables have the same values with the same 'meanings' (for instance, in the case of Likert-scaled items), and this can be made explicit by attaching the same label to these variables. Note that 'status' refers to the name of the variable and 'mstatus' to the name of the label (both names may be identical, by the way). Label define mstatus 0 'unmarried' 1 'married' Therefore, two command lines are necessary Giving labels to values works like this: You first have to define one or several labels in a second step the label(s) is or are attached to one or several variables. This command, which may be abbreviated as la var, has to be repeated for each variable that is to be labeled.
