Stata command: Scalar

[Patrick Royak]

Hey Guys,

i am a master's degree student in finance. For my master thesis i model the value at risk. For this, i need a create a scalar. For example i have a time series with 1000 observations with intervals of 250 observations. To model the value at risk, i need the volatility for the day n+1 (this means for the day 251). Then from 2-251 and i need the volatility of 252 and so on. Can u help me by this issue? Or is there another possibility?

Thank you in advance for your help.

King regards

Many threads here on rolling calculations for such data. Did you search the forum for mentions of volatility?

(What you want sounds like a variable to me, not a scalar.)

Thank you for your hint. I created a new variable under a condition and it worked.
