Diagnostic knowledge-based systems are used in a variety of application domains to support classification decisions. The effectiveness of such systems often decreases as the application environment or user preferences change over time. Hence, frequent adjustments to the system knowledge by a...

We analyze and compare the errors of two numerical approaches for measuring compensated income. We prove that Vartia’s algorithm and Breslaw and Smith’s algorithm both converge quadratically; when the price change within each partition step is small, the error of Vartia’s algorithm is...
