一个常见的问题，在检查已确定的模型是如何测试可能的零极点相消。一个系统的方式进行这样的测试，考虑到模型参数的不确定性建议。特别是，被认为是最小二乘识别模型的应用。该方法是一种有效的方法，应用广义最小二乘法。
A common problem in examination of identified models is how to test possible pole-zero cancellations. A systematic way of performing such tests taking the uncertainty of the model parameters into account is suggested. In particular, application to models obtained with least squares identification is considered. The proposed method turns out to be an efficient way of applying the generalized least squares method.
