WebOct 22, 2004 · Generalized additive models for extremes may be estimated by using penalized likelihood (Green and Silverman, 1994). Suppose that a threshold u has been chosen, and that over the period (0, t 0 ) independent exceedances w j over u have been observed at times t j with associated co-variates x j , for j = 1,…, n . WebMay 12, 2008 · We propose an iterative estimation procedure for performing functional principal component analysis. The procedure aims at functional or longitudinal data where the repeated measurements from the same subject are correlated. An increasingly popular smoothing approach, penalized spline regression, is used to represent the mean function.
