Abstract
Predictive regressional models like DPCM are widely used in digital signal compression. This paper analyzes the relationship that exists between the p redictive model fitness and the resultant reduction of the first-order sign al entropy, and finds the lossless compression ratio C as a function of pre dictive model correlation rho.
