From this time to about 4400 yr cal BP, a comprehensive set of proxies revealed a highly variable scenario, with alternating lagoon states linked to climatic variability.
We used a set of proxies (pollen, plant-macrofossils, charcoal) to reconstruct the long-term vegetation and fire histories at different spatial scales.
A permafrost tunnel in the Vault Creek Valley Chatanika River Valleyy, near Fairbanks) exposes a sequence of frozen deposits and ground ice that provides a comprehensive set of proxies to reconstruct the late Quaternary environmental history of Interior Alaska.
On the other hand, when unique personal identifiers (such as social insurance number or personal health number) are not available, the linkage and correct linkage rates depend heavily on the uniqueness of a set of proxies (such as name, sex and date of birth).
It is for these sorts of reasons that I have always advocated 'multiproxy' reconstructions, which attempt to pull information from a diverse complementary set of proxy sources (tree-rings, corals, ice cores, speleothems, sediments, etc).
In an effort to better understand how environmental dynamics were linked to the cultural record, a set of proxy records (diatoms, opal phytoliths, gastropods, shells) were introduced to take into account local environmental evolution data according to global and regional environmental evolution models.
Plink v 1.0.7 selects a set of proxy SNPs (using the reference sample information) and then phases these SNPs in both reference and test samples jointly.
First, a latent construct has to be measured through a set of proxy variables.
An index of comorbidity level has the advantage of bringing several comorbidities into a single numeric score, thereby reducing the number of candidate variables into a manageable set of proxy variables, which is especially beneficial when using administrative databases or medical registries [ 4, 5].
The wealth status is estimated from a set of economic proxies [71], [72], [73], [74], [75], by using the Principal Component Analysis (PCA).
Specifically, we used a binomial Generalized Additive Model for exploring the relation between the occurrence of the invasive species and a set of PAB proxy variables derived from high-resolution remote sensed imagery (LiDAR – Light Detection and Ranging – and orthophotos).
