Forecasting Realized Volatility Using a Nonnegative Semiparametric Time Series Model
This paper introduces a parsimonious and yet flexible nonnegative semiparametric model to forecast financial volatility. The new model extends the linear nonnegative autoregressive model of Barndorff-Nielsen & Shephard (2001) and Nielsen & Shephard (2003) by way of a power transformation. It...

This paper introduces a parsimonious and yet flexible nonnegative semiparametric model to forecast financial volatility.

It is semiparametric in the sense that the distributional form of its error component is left unspecified. The statistical properties of the model are discussed and a novel estimation method is proposed. Asymptotic properties are established for the new estimation method.
