From: Multivariate analysis of genomic variables, effective population size, and mutation rate
Exploratory factor analysis of genomic variables and Neu. a An EFA plot is generated from the standardized dataset by using factanal function and varimax rotation in R software on raw data. b An EFA plot is generated from phylogenetically independent contrasts by applying factanal function and varimax rotation. Two factors were considered as latent variables. The genomic variables and Neu are regarded as manifest variables. The genomic variables showed no relationships with Neu in raw data but in phylogenetically independent contrasts, only association between Neu and Average introns per gene is observed
