pctab for Creating Percentage Tables
pctab command is a new tool in Stata that makes it easy to generate percentage tables from your data. With just one line of code, you can produce a neatly formatted table showing percentages of different variables broken down by a grouping variable.
The syntax for pctab is simple:
asdocx pctab varlist, by(groupby)
- varlist is a list of variables for which you want percentages calculated. These will become the rows in your table.
by()specifies a single grouping variable. This will create a separate column for each unique value of the grouping variable.
For example, say we have survey data on industry, marital status, and education level. To generate a table showing the percentage of people married, never married, and with a college degree within each industry, our code would be:
* Load example dataset sysuse nlsw88, clear * Create percentages of variables by industry asdocx pctab married never_married college_grad, by(industry)
pctab is designed to automate and simply a common task that often requires more complex code. By specifying your variables and groups, it handles all the calculations and formatting behind the scenes. The resulting table makes it easy to see percentages and comparisons at a glance.
This new command eliminates the need for manual tabulations and formatting, allowing you to go from data to publication-ready tables with ease. I expect
pctab will be a frequently used tool for Stata users who work with survey data and need to present descriptive statistics.
