ICIcombined {aws} | R Documentation |
The function performs adaptive smoothing by Intersection of Confidence Intervals (ICI) using multiple windows as described in Katkovnik et al (2006)
ICIcombined(y, hmax, hinc = 1.45, thresh = NULL, kern = "Gaussian", m = 0,
sigma = NULL, nsector = 1, symmetric = FALSE, presmooth = FALSE,
combine = "weighted", unit = c("SD","FWHM"))
