st: Moving Standard Deviation

Hello, I am currently trying to generate the moving standard deviation for a measure of volatility. I have used the mvsumm command, however, I am not sure how to cite that in the paper I am writing. I am trying to reproduce the following formula used in the literature.
                   Vol= [1/m*(sum(lne_t+i-1 - lne_t+i-2)^2)]^1/2

where lne is the log of the exchange rate. Any help with this issue would be hugely appreciated.

Best regards,
