One such method includes applying a decomposition algorithm, by a processor, to an Nth-order tensor representing data, wherein N ≥ 2, to generate, from at least two submatrices A and B of the tensor, eigenvectors of each of AAT, ATA, BBT, and BTB; where the data comprise indicators, represented in respective rows and columns of the tensor, of values of at least two index parameters; and determining an indicator of a health parameter of a subject, the determining being based on the eigenvectors and on values, associated with the subject, of the at least two index parameters.
