“…different transfer-function models, different data-sets, different records, different proxies) (Birks 1998). More sophisticated smoothers such as SiZer (significance of zero crossing of the derivative) (Chaudhuri & Marron 1999;Holmström & Erästö 2002) and the related BSiZer (Erästö & Holmström 2005) have considerable potential in palaeoclimatology because they can assess which features seen in a range of smoothed data are statistically significant and thus may be environmentally significant (see Korhola et al 2000;Erästö & Holmström 2005Weckström et al 2006 for palaeoecological applications). Given the random walk simulations of pollen data presented by Blaauw et al (2010), there is an increasing need to use techniques such as SiZer or BSiZer to distinguish signal from random red noise in stratigraphical time-series.…”

“…However, such a point-wise inference is bound to result in a large number false positives, and we therefore use simultaneous inference over all times t k and a fixed σ. The simultaneous inference technique applied is the method of highest pointwise probabilities (HPW), first described in Erästö and Holmström (2005). The HPW is a greedy algorithm that selects time points according to their descending order of marginal posterior probability until the joint posterior probability of correlations being positive or negative is at least α.…”

“…This method was extended by Erästö and Holmström [2005], who incorporated Bayesian methods for identifying multiscale features. These methods have found applications in the analysis of climate data [Divine et al, 2007;Godtliebsen et al, 2003;Korhola et al, 2000;Rohling and Pälike, 2005] such as the reconstructed past temperature record.…”
