dipca: Dynamic Inner Principal Component Analysis
Methods for dynamic inner principal component analysis (DiPCA), dynamic inner canonical correlation analysis (DiCCA), and dynamic inner partial least squares (DiPLS) for multivariate time series. These methods extract latent components that follow autoregressive models, enabling temporal prediction and reconstruction. Based on Dong and Qin (2018) <doi:10.1016/j.jprocont.2017.05.002>, Dong and Qin (2018) <doi:10.1016/j.ifacol.2018.09.379>, and Dong and Qin (2018) <doi:10.1016/j.jprocont.2018.04.006>. Integrates with the 'multivarious' package for consistent preprocessing and projection interfaces.
