There are three ways to put frequencies in a new variable:
- tabulate oneway or tabulate twoway will save counts as a matrix. svmat can be used to create variables from the matrix.
- Use the collapse command. You may have to merge the resulting variables back with the original dataset if you want to have them both together. ...
- Use egen ... = count (1), by (...). ...

How do I make a frequency plot in Stata?
Frequency plots can be made in Stata using the hist command with the freq option. However, if the variable you are graphing takes on noninteger values, this command will not work. An alternate solution would be to create a group variable, and then use the graph command with the freq, hist, and bin () options.
How do I tabulate data in Stata?
Stata offers a variety of ways to tabulate data. The most basic table, table [variable], will show the variable and the frequencies of each category, like so. This can also be done with more than one categorical variable, table [variable1] [variable2] [variable 3] [variable etc].
What is a frequency table in statistics?
Frequency tables display the values of a variable, weighted with the number of occurrences of each single value. In addition, percentages are displayed. will display a frequency table including percentages and cumulative percentages. Note that if you want to use probability weights with your data, tabulate can be used with the svy prefix.
What does the contract command do in Stata?
In the sample code above, the contract command makes all combinations of designated variable lists ( foreign , rep78) about frequency or percentage. The zero option includes combinations that have 0 frequency, the freq (count) option names the variable count, and the nomiss option tells Stata to drop any observations that contain missing values.
How do you construct a frequency table?
StepsTo make the frequency distribution table, first write the categories in one column (number of pets):Next, tally the numbers in each category (from the results above). ... Finally, count up the tally marks and write the frequency in the final column.
What is a frequency table in Stata?
A frequency table shows the distribution of observations based on the options in a variable. Frequency tables are helpful to understand which options occur more or less often in the dataset. This is helpful for getting a better understanding of each variable and deciding if variables need to be recoded or not.

Can you tabulate multiple variables in Stata?
In multiway tabulations, you can display frequencies across levels of two or more variables. You can have levels of one variable nested within levels of another variable in columns, in rows, or in both dimensions.

Stata does not have a command to calculate the mode, though rarely do people care about the mode so this usually isn't a problem. You may have noticed that the summarize command also calculates the standard deviation, and variance with the details option.

Question
I have a variable that I can tabulate to get the frequencies and percent and cumulative percent frequencies of its different values, but what I really want to see are the cumulative frequencies. Any suggestions?
Answer
The question shows that no matter how many general or special purpose tabulation commands Stata provides, it is always possible to think of a tabulation problem that is not directly supported.
