The Effect of Omitted-Variable Bias on the Evaluation of Compiler Optimizations
Todd Mytkowicz, Amer Diwan, Matthias Hauswirth, Peter F. Sweeney · Computer · 2010
Experiments that do not account for all relevant variables can produce misleading results. The authors identify two variables that compiler optimization evaluations often omit, resulting in significant omittedvariable bias, and discuss how to identify new OVB sources and incorporate them in an experimental design.
