Additionally, mean imputation reduces the variability of the data, increasing bias and underestimating uncertainty in the model.

Orthogonal rotation methods like Varimax or Promax aim to align the principal axes with the original variables, simplifying the interpretation of component loadings. By rotating the components, PCA seeks to achieve a clearer separation of variance, making it easier to identify and understand the underlying patterns or structures in the data. Without rotation, the components may remain in their original orientation, making them less interpretable and potentially requiring more components to capture the same amount of variance.
