摘要： A method of compressing and reconstructing a large amount of data using statistical analysis is provided. For a large amount of distribution data with respect to a relatively small number of entries having correlations, a correlation matrix and/or a factor loading matrix is obtained from the large amount of original data using a multivariate analysis and stored as compressed data. Data having the format and tendency of the original data is reconstructed using the factor loading matrix and a random-number matrix. Accordingly, data can be compressed to a predetermined capacity and then reconstructed regardless of the amount of data, advantageously allowing for efficient management of a large amount of data.
