Delete data that does not meet a condition

starkey09 — Wed, 21 Nov 2018 05:00:14 GMT

I have a large dataset in excel to sort for firms stock data. On one sheet I have returns, sheet 2 has market cap, sheet 3 has dividend yield. Because not all companies pay dividends, I need to delete firms that are not included on the dividend yield sheet. Is there a procedure I can run in sas that will only count firm data that is included in all dataset sheets?

You can filter your data relatively easy via PROC SQL.

It would be as a simple as

Proc sql;
Create table filtered as
Select * from returns
Where firm in (select distinct firm from dividend);
Quit.

You would have to replace the table and variable names as appropriate.

Thanks. That works to filter the names. However, the data that is attributed to each of those firm names is missing. The result gave me just a list of the names on the data set. I have attached a photo- perhaps I made an error?

Your code doesn't match mine. I have select * which means select everything and you have select name, which selects only the name variable. Please post your code and results as texts, trying to read code off images is not fun.

Thank you very much. That has worked perfectly.
