WebThe aims of this exercise are to learn how to use R to perform Phylogenetic Generalised Least Squares (PGLS) analyses. We will be using the evolution of eye size in frogs as an example. The data and modified tree come from Thomas et al. ( 2024), and the original tree comes from Feng et al. ( 2024).

WebMay 9, 2016 · Generalized linear models are an extension of OLS. In both there is a linear relationship between the "dependent" variable and the explanatory variables of the form: y = β 0 + β 1 x 1 + β 2 x 2 +... β n x n + ε or y = X β. In generalized linear models, though, ρ = X β, so that the relationship to E ( Y) = μ = g − 1 ( ρ).

WebPhylogenetic Generalized Least Squares in R Here we give an example PGLS analysis using a tree and data from the ade4 package. We analyse the data using functions from the ape and nlme packages. There are several other ways to conduct PGLS analyses in R, most notably using the pgls function in the caper package. knotting in textileWebIn statistics, generalized least squares(GLS) is a technique for estimating the unknown parametersin a linear regressionmodel when there is a certain degree of correlationbetween the residualsin a regression model.
