"Using the chi-square statistic," observes one professor, "Obama's and Ayers's books were indistinguishable, while Obama's book was easily distinguishable from books by other authors."
Writes another analyst, using his own proprietary software, "There is a strong likelihood that the author of "Fugitive Days" ghost-wrote "Dreams From My Father" using recordings of dialog (either tape recorded or notes). Alternatively, another scenario could be possible: Ayers might have served as a 'book doctor.'"
One systems engineer writes, "The statistical style analysis performed by our research team suggests that the writing style of 'Dreams From My Father' is significantly more similar to the style observed in 'Fugitive Days' than to the style found in other works by Barack Obama such as 'Audacity of Hope.'"
He continues, "Even more interesting, when we extract those sections of 'Dreams From My Father' that Dr. Cashill believes to be Ayers' writing and treat this as a unique document, the style analysis software identifies a stronger correlation between this sample and Ayers' 'Fugitive Days' than we see between this same sample and the remainder of 'Dreams From My Father'!
Thus we have reason to believe that 'Dreams From My Father' had at least two authors, and one author's measured style features more closely match those of Ayers than they match those of the other author(s)."
"Under the Q-value statistic," argues one university-based analyst who tested "Dreams" against Ayers' 2001 memoir, "Fugitive Days," "segments of 'Dreams' consistently compared as well with 'Fugitive' segments as it did with other segments of 'Dreams' itself. In contrast, 'Dreams' compared poorly with other documents."
