Understanding temporal aggregation effects on kurtosis in financial indices
Lieberman, Offer; Phillips, Peter C. B. - 2018
Indices of financial returns typically display sample kurtosis that declines towards the Gaussian value 3 as the sampling interval increases. This paper uses stochastic unit root (STUR) and continuous time analysis to explain the phenomenon. Limit theory for the sample kurtosis reveals that...
