Abstract

The present invention has: an acquisition means that acquires measurement data pertaining to periodic movement of a physical object that performs periodic movements; a determination means that determines a revision coefficient, which is a coefficient in a revised autoregressive model, on the basis of the measurement data acquired by the acquisition means; and a diagnosis unit that diagnoses an abnormality in the physical object on the basis of the revision coefficient determined by the determination means. The revised autoregressive model is a formula for deriving a prediction value of the measurement data on the basis of the measurement data pertaining to the periodic movement of the physical object and the revision coefficient for the measurement data. The determination means determines the revision coefficient on the basis of eigenvalues of an autocorrelation matrix derived from the measurement data, the eigenvalues being derived by performing singular value decomposition on the autocorrelation matrix.
