自本刊1993年第3期刊登了吴国芳的《一个不妥的例题》和第8期的何秀余的《也谈〈一个不妥的例题〉》两篇文章后,陆续收到了不少读者的来信,认为吴国芳和何秀余两位同志虽然指出了《社会经济统计学原理》一书中所举例题的不妥之处,但其论证仍不够完整. Since the publication of Wu Guofang’s “An inappropriate example” and the 8th issue of He Xiuyu’s “Also Talk about an Inappropriate Case” in the 3rd issue of 1993, many readers have been received. I believe that the two comrades Wu Guofang and He Xiuyu pointed out the inaccuracies of the examples cited in the “Principles of Social Economic Statistics”, but their arguments are still not complete.
