A Wavelet‐Based Extension of Generalized Linear Models to Remove the Effect of Spatial Autocorrelation. 基于小波扩展广义线性模型消除空间自相关的影响

Biogeographical studies are often based on a statistical analysis of data sampled in a spatial context. However, in many cases standard analyses such as regression models violate the assumption of independently and identically distributed errors. In this article, we show that the theory of wavelets provides a method to remove autocorrelation in generalized linear models (GLMs). Autocorrelation can be described by smooth wavelet coefficients at small scales. Therefore, data can be decomposed into uncorrelated and correlated parts. Using an appropriate linear transformation, we are able to extend GLMs to autocorrelated data. We illustrate our new method, called the wavelet‐revised model (WRM), by applying it to multiple regression with response variables conforming to various distributions. Results are presented for simulated data and real biogeographical data (species counts of the plant genus Utricularia [bladderworts] in grid cells throughout Germany). The results of our WRM are compared with those of GLMs and models based on generalized estimating equations. We recommend WRMs, especially as a method that allows for spatial nonstationarity. The technique developed for lattice data is applicable without any prior knowledge of the real autocorrelation structure.     

Sourcing archaeological bitumen in the Olmec region

Prehispanic Mesoamerican peoples collected, processed, and used bitumen for decoration, sealant, and adhesive. Among the earliest to do so were the Olmec (1200–500 b.c.) of Mexico's southern Gulf coastal lowlands. Geochemical analysis of bitumen from Olmec archaeological contexts as well as from seeps in the Olmec region reveals that seeps can be geochemically differentiated and can be correlated with archaeological samples. Groups of sites with chemically different archaeological bitumen indicate multiple procurement networks reflecting complex regional systems of exchange and interaction. Organic geochemical analysis of bitumen provides a new tool to study procurement strategies and exchange patterns in Mesoamerica.
