NettetMultilinear principal component analysis ( MPCA) is a multilinear extension of principal component analysis (PCA). MPCA is employed in the analysis of M-way arrays, i.e. a cube or hyper-cube of numbers, also informally referred to as a "data tensor". M-way arrays may be modeled by. linear tensor models such as CANDECOMP/Parafac, or. Nettet11. apr. 2024 · I agree I am misunderstanfing a fundamental concept. I thought the lower and upper confidence bounds produced during the fitting of the linear model (y_int above) reflected the uncertainty of the model predictions at the new points (x).This uncertainty, I assumed, was due to the uncertainty of the parameter estimates (alpha, beta) which is … tips for middle school success https://pipermina.com
