Effects coding in discrete choice experiments
指出在离散选择实验中使用虚拟编码时可能出现的误解问题，并通过两个例子说明效应编码如何解决这些问题。
This paper discusses the inherent problems associated with applying dummy coding when including a fixed comparator in a discrete choice experiment, and seeks to illustrate the misinterpretations that may arise if the analyst is not aware of the problem. This note provides two examples of possible misinterpretations with dummy coding and how it is solved with the use of effects coding.
