在F.H.C Marriott写过的书《The interpretation of multiple observations》中有一段话,可能是很多相关统计工作者应该注意到的: If the resluts disagree with informed opinion, do not admit a simple logical interpretation, and do not show up clearly in a graphical presentation, they are probably wrong. There is no magic about numerical methods, and many ways in which they can break down. They are a valuable aid to the interpretation of data, not sausage machines automatically transforming bodies of numbers into packets of scientific fact.
