: rown colSum m x n matrix 行空間/個体空間 列空間/変数空間 Generating the space means generating axies, dim1….dimn. > these dimn has inertias or variances which are disassembled from the total variance of inputed table. > these inertial of dims are the same in Row space and Col spece.
D α Vt • U related to Row coordinate • V related to Col coordinate • αis singular value(square root of eigen value) excepcted matrix residuales diag matrix, items are inverted squared row margin diag matrix, items are inverted squared col margin standardization
