Testing multiple linear regression systems with metamorphic testing

Regression is one of the most commonly used statistical techniques. However, testing regression systems a great challenge because absence test oracle in general. In this paper, we show that Metamorphic Testing an effective approach to multiple linear systems. doing so, identify intrinsic mathematical properties regression, and then propose 11 Relations be for testing. Their effectiveness examined using mutation analysis with range different programs. We further look at how could adopted more way. Our work applicable examine reliability predictive based on has been widely economics, engineering science, as well calculation manipulated by users.
