Claim 3:
4. The data-compression analyzer of claim 1 further comprising;
a threshold optimizer comprising:
a trainer that applies a plurality of training data blocks to the counter, causing the calculator and multiplier to generate a plurality of CV*NZ products for the plurality of training data blocks;
wherein a compression ratio is received or generated for each training data block in the plurality of training data blocks, the compression ratio for a training data block being a ratio of a size of the training data block after compression to a size of the training data block;
a tabulator that tabulates the plurality of CV*NZ products as a function of the compression ratio for each of the plurality of training data blocks;
a Receiver Operating Characteristic (ROC) tabulator that compares the plurality of CV*NZ products to the horizontal threshold to obtain predicted results, and compares the compression ratio for each training data block to a vertical threshold to obtain actual results, and generates true and false positive rates from the predicted and actual results;
an ROC optimizer that selects an optimal combination of the true and false positive rates and outputs a test value of the horizontal threshold corresponding to the optimal combination as the horizontal threshold for use by the comparator for input data blocks.
