Stated choice surveys are used to figure out what people prefer when given options. Sometimes, these surveys have a problem where one option is clearly better than the others, which can mess up the results. Researchers found a way to detect and fix this issue by using a new method called minimum regret. By doing this, they made a new model that can account for these problems and give more accurate results. This new approach helps make sure that the choices people make in surveys are fair and balanced.
