In this paper, we put forward a new reliable method called probabilistic principal component analysis (PPCA) to impute the missing flow volume data based on ...
Principal Component Analysis with Missing Data | by Seb Bailey
Traditional PCA will not accept any missing data points. Data points will be scored by how well they fit into a principal component (PC) based upon a measure ...
Can we believe in the imputations? - R-bloggers
The rough idea is to project all the multiple imputed datasets on the PCA graphical representations obtained from the “mean” imputed dataset.
