We shall look into the steps involved in the process of PCA. … WebbPCA creates uncorrelated PCs regardless of whether it uses a correlation matrix or a covariance matrix. Note that in R, the prcomp () function has scale = FALSE as the default setting, which you would want to set to TRUE in most cases to standardize the variables beforehand. – user3155 Jun 4, 2024 at 14:31 Show 5 more comments 61
WebbPOD and PCA. The main use of POD is to decompose a physical field (like pressure, temperature in fluid dynamics or stress and deformation in structural analysis), depending on the different variables that influence its physical behaviors. As its name hints, it's operating an Orthogonal Decomposition along with the Principal Components of the field.
