WebJun 21, 2024 · Redundancy Analysis (RDA) 21/jun/2024 This file explains the procedure followed by Ernesto Igartua to perform redundancy analysis on genetic features of the genotypes (probability of belonging to each one of the four germplasm groups), explained by geographic and agro-climatic features of the locations of collection of the genotypes. WebRedundancy Analysis (RDA) is a direct extension of multiple regression, as it models the effect of an explanatory matrix X X (n x p) on a response matrix Y Y (n x m). The difference here is that we can model effect of an explanatory matrix on a response matrix, rather …

WebWe compare redundancy analysis to pcadapt, which is a nonconstrained ordination method, and to a latent factor mixed model (LFMM), which is a univariate genotype-environment association method. Individual-based simulations identify evolutionary scenarios where RDA genome scans have a greater statistical power than genome scans based on PCA. WebRDA RDA analysis.
