We showed that GVAD has the downside of increasing the variance of the parameter estimates by a factor related to the size of the window used to estimate the slope, and quantified precisely a tradeoff inherent in this approach: smaller windows lead to more noise in the fitting process, whereas larger windows lead to more aliasing errors.
10: An extension to GVAD to reduce variance by increasing the window size, at the cost of being slightly less robust to aliasing errors.
By adding the simple dealias-and-refit local search procedure, GVAD+LOCAL performs much better than GVAD alone.
