Review of the Randich-Grant Article

Metallurgy (Dr. Randich)
Statistics (Dr. Grant)

    Both sections of the article failed to make their case. The metallurgical section contained a huge gap in its logic (proposing an explanation but failing to support it quantitatively), and predicted at least two features of the elemental data that were the opposite of that actually observed. The statistical section started well, but stumbled when it confused heterogeneity with analytical uncertainty and when it used confidence intervals instead of difference in means to assess the separation of the two groups of crime-scene fragments. Fixing these two errors gave the opposite result, i.e., confirmed that the groups were distinct.
    Thus we are back to the situation before this article was publishedthe two groups of fragments are real, and represent two and only two MC bullets. The Latter-Day NAA Revisionism has failed.
