Responses and Degrees of Freedom of PVAR for a Continuous Power-Law PSD
This paper is devoted to the use of the Parabolic Variance (PVAR) to characterize continuous power-law noises. First, from a theoretical calculation, we give the responses of PVAR extended to continuous power-law noises. Second, from an empirical study, we provide an approximated but relevant expression of the uncertainties of PVAR estimates. This simple expression easily applies to continuous power-law noises.
