![]() ![]() ttest mpg, by(foreign) Two-sample t test with equal variances Ttest, by(foreign) command, and the output labels the groups as domesticĪnd foreign (instead of 0 and 1). Value labels are used in other commands as well. Now when we use the tabulate foreign command, it shows the labels domestic car andįoreign car instead of just 0 and 1. describe Contains data from /stata/modules/autolab.dtaįoreign byte %12.0g foreignl the origin of the car, foreign or domestic If we use the describe command, we can see that the variable foreign has a value label calledįoreignl assigned to it. The label values command below associates the variable foreign with the label label define foreignl 0 "domestic car" 1 "foreign car" Label define command below creates the value label called foreignl that associates 0 withĭomestic car and 1 with foreign car. This is a two step process where you first define the label, and then you assign the label to the variable. Let’s make a value label called foreignl to label the values of the variableįoreign. Rep78 int %8.0g the repair record from 1978įoreign byte %8.0g the origin of the car, foreign or domestic Mpg int %8.0g the miles per gallon for the car Price int %8.0gc the price of the car in 1978 describe Contains data from /stata/modules/autolab.dta The describe command shows these labels have been applied to the variables. label variable rep78 "the repair record from 1978" label variable price "the price of the car in 1978" label variable mpg "the miles per gallon for the car" label variable foreign "the origin of the car, foreign or domestic" Let’s use the label variable command to assign labels to the variables Obs: 74 This file contains auto data for the year 1978 The describe command shows that this label has been applied to the version that is currently in memory. label data "This file contains auto data for the year 1978" This label can be up to 80 characters long. Let’s use the label data command to add a label describing the data file. Variable name type format label variable label Size: 3,478 (99.9% of memory free) (_dta has notes) Let’s use the describe command to verify that indeed this file does not have any labels. Let’s use a file calledĪutolab that does not have any labels. 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). (type ssc install splitvallabels to install)Beyond work-arounds, perhaps the most valuable addition would be that any graph option that handles a value label might have an extra option that specifies a maximum preferred chunk size or a preferred number of chunks.This module will show how to create labels for your data. INSTALLATION FILES (type net install splitvallabels) This will createĪuthor: Nick Winter, University of Virginia Up these long labels and packages them in a format appropriateįor specification as part of a relabel option. Labels can overlap each other in the graph. Variable in, for example, a bar graph has long labels, these Multiple chunks, and returns those chunks in a form appropriateįor specification as part of a graph command. Splitvallabels splits the value labels for a variable into 'SPLITVALLABELS': module to split up value labels for multi-line graph labelling ![]()
