The author concludes that, although the method of "multivariate statistical analysis" has the similar motive and working mechanism with symptom complex diagnosis, they have their own limits in application: sometimes the limit can be conquered when the methods applied combined, but some of the limits can not be conquered, so we should grasp the methods neatly in practice.

但是，由于各种多元统计分析方法自身的特点，在具体的应用中又都存在着各自的局限，有些通过几种方法联合应用可以克服，但有些却是克服不了的，在实际应用中要灵活掌握。
