Modulated Realized Variance (MRV) is an integrated variance estimator introduced by Podolskij and Vetter. It is based on the concept of multipower variation and assumes additive noise structure.

1 2	variance_mrv(estimator) variance_mrvRolling(estimator,wLength=23400)

`estimator`	Vector of (time, price) observations for market asset when external market data is used.
`wLength`	Length of a rolling window for rolling estimators. Default window length is 23400 (number of seconds in a trading day)

- Convergence speed: m^{1/4} (m - number of observation)

- Accounts for additive noise: yes

- Accounts for finite price jumps: no

- Accounts for time dependence in noise: no

- Accounts for endogenous effects in noise: no

a numeric vector of the same length as input data.
