数据造假新手段“P值黑客”.

刚刚更新 编辑: 浏览次数:251 移动端

  P-hacking rers to the practice of manipulating scientific data so that the results appear to be statistically significant.

  “P值黑客”是指操作科学数据,从而使结果看上去具有统计学意义的行为。

  这个词最早由宾夕法尼亚大学的西蒙松教授提出,一起来看看他是怎么说的:

  Professor Uri Simonsohn of UPenn discussed what he rers to as "p-hacking." P-hacking is the idea that if researchers are engaging in questionable analysis practices, then they should have a disproportionate number of findings at or close to the p < .05 threshold for statistical significance, and that this can be relatively easy to detect.

  宾夕法尼亚大学西蒙松教授谈到他所指的P值黑客。P值黑客是指如果研究人员采用的分析方法可疑,那么他们应当有一个不成比例的P值数据结果等于或接近p<0.05这个统计学意义阀值,而这也相对很容易被发现。

  虽然直译为“P值黑客”,但从定义上看,该词有“数据造假”的意思,这点可以从《大西洋月刊》上的文章《自我修正的科学之谜》(The Myth of Self-Correcting Science)中的解释得到佐证:

  Almost more alarming than the few individuals committing academic fraud are the high percentage of researchers who admitted to more common questionable research practices, like post-hoc theorizing and data-fishing (sometimes rerred to as p-hacking), in a recent study led by Leslie John.

  近期由莱斯利·约翰主导的研究指出,比少数人的学术欺诈行为更令人担忧的是,有很高比例的研究人员承认他们的做法更普遍更不靠谱,如事后推理和数据造假(有时指P值黑客)。
