How to caclulate "scaled by the square root" with stata

[Cristiana LI]

Hi everyone.
Would you please someone help me with how to use stata commend to generate a variable ATF= "Audit and audit-related fees scaled by the square root of total assets"?
Many thanks!

The answer will depend on your data and what exactly this means.

Is total assets already a variable?

Is total assets to be calculated for the entire dataset or for subsets, e.g. years, sectors, companies, whatever?

The function sqrt() is likely to be useful whichever way the answer runs.
