ABSTRACT:
Data compression and decompression are performed on a series of data points, by expressing a plurality of data points as an equation or a series of equations. Variable accuracies, and accordingly variable compression ratios, may be provided. Multiple versions of the compressed data, with corresponding multiple accuracy levels, and resulting multiple decompressions may be displayed for comparison. The method and apparatus may be used for storing network statistical data.
