当采用传统方法时，其分析结果极易产生偏差，因此变量含误差模型(error-in-variables, EIV)逐渐受到统计学界的关注，目前对于变量含误差模型的参数估计一直是该领域的热点。

But it was neither able to tell us in which procedure the error occurred, nor which variables may have been involved.
但是它既不能告诉我们错误发生在哪个过程当中，也不能告诉我们牵涉到哪些变量。
Once you find the line of code in question, determine the value of the variables in that method, how the method was called, and specifically why the error occurred.
一旦您发现了代码中出错的行，请确定该方法中变量的值、方法被调用的方式以及关于错误如何发生的详细情况。
Remember that error-checking only happens during marshalling -- this means that erroneous data can be floating around in these member variables while they are in memory, awaiting marshalling.
要知道错误检查只有在编组时进行，这意味着只要还在内存中，错误数据就可以自由地存在于这些成员变量之中等待编组。
