How many variables are in a dataset Stata?

There’s a limit of 2,047 variables in Stata/IC, 32,767 in Stata/SE, and 120,000 in Stata/MP. You can have as many observations as your computer’s memory will allow, provided you don’t go too far above 2 billion cases with Stata/SE and 1 trillion with Stata/MP.

What is an observation in Stata?

To refer to a variable in Stata, you simply type its name. To refer to a particular observation in a variable, you type varname[n], where n is the observation number. For example, observation 7 in variable GDP could be called by typing GDP[7].

How to sum a row of data (stock price) on Stata?

how can i sum a row of data (stock price) on stata? I tried to looked up with help functions and some youtube video but couldn’t find any helpful resources. use egen x=rowtotal (x1 x2 x3) for the summation in the row (must provide a variables list) and collapse (sum) x to compute a total of the column.

How can I use Stata to work with my data?

We can copy and paste easily into our own Stata to work with your data. If your dataset is confidential, then provide a fake example instead. The second best way to explain your situation is to use one of Stata’s own datasets and adapt it to your problem. Examples are the auto data and the Grunfeld data (a simple panel dataset).

How to sum the total of a column in a table?

use egen x=rowtotal (x1 x2 x3) for the summation in the row (must provide a variables list) and collapse (sum) x to compute a total of the column. Thanks for replying Sergiy. I still not quite get how to write the syntax.

Does Stata freeze when values vary for each observation?

I found this Stata: Using egen, anycount () when values vary for each observation however Stata freezes as my dataset is quite large (100.000 rows and 3000 columns).
