Dataset and R Code for Species-level Avian Influenza Phylogenetic Generalized Least Squares Regression
<p>Dataset for Species-level Avian Influenza Phylogenetic Generalized Least Squares (PGLS) Regression:<br> Variables include taxonomic information for each species, # of IAV-positive individuals, # of IAV-tested individuals, the prevalence of IAV, the proportion of diet made up of different food types, the proportion of foraging time spent in different strata (below water, water surface, ground, understory, etc), sampling-related variables (mean latitude, mean date, the proportion of hatch year individuals), migration and territoriality category, climatologic variables, mean clutch size, and mating system.</p> <p>R Code for PGLS and Avian Influenza Prevalence ContMap.</p>

<p class="MsoNormal"><span>Phylogenetic generalized least squares (PGLS) regression is widely used to detect evolutionary correlations. In contrast to the equal treatment of analyzed traits in conventional correlation methods such as Pearson and Spearman's rank tests, we must designate one trait as the independent variable and the other as the dependent variable. However, in our PGLS regression analyses (using Pagel's <em>λ</em> model) of both empirical and simulated datasets, switching independent and dependent variables yielded many conflicting results. A serious problem with PGLS regression that has not been noticed before is that selecting an inappropriate trait as the dependent variable will often result in an error. To assess correlations in simulated data, we established a gold standard by analyzing changes in traits along phylogenetic branches. Next, we tested seven potential criteria for dependent variable selection: log-likelihood, Akaike information criterion, <em>R</em><sup>2</sup>, <em>p</em>-value, Pagel's <em>λ</em>, Blomberg et al.'s <em>K</em>, and the estimated <em>λ</em> in <a name="_Hlk136010442"></a>Pagel's <em>λ</em> model. We determined that the last three criteria performed equally well in selecting the dependent variable and were superior to the other four. For practicality, we suggest using the trait with a higher <em>λ</em></span><span> or <em>K</em> </span><span>value as the dependent variable in future PGLS regressions. In analyzing the evolutionary relationship between two traits, we should designate the trait with a stronger phylogenetic signal as the dependent variable even if it could logically assume the cause in the relationship.</span></p>
