In this paper, the authors propose the statistical method to give us information about the balance of the subjects on the ship. As the consequense of the cross-correlation and cross-spectral analysis, we got inferences that statistical characteristics when subjects can't keep his balance, it is significantly different from the one that subjects can maintain his balance stable. The large changes of these statistics occur from several seconds before off-balance. Based on this result, we-show that these information can be compounded to the component of eigenvector of correlation matrix. The application of this method to our data showed that the movement of eigenvectors which correspond to the largest and the secondary largest eigenvalue could evaluate the condition of balance and forecast when human body can't keep balance.
