Should we rewrite the autism rule book? 15 March 2012 By Fred Volkmar and Francesca Happé (Two “different” opinions?) http://www.newscientist.com/article/mg21328555.500-should-we-rewrite-the-autism-rule-book.html Bill or others:  If you are reading this, is Fred talking about STATS & Probability when he states:  “The way DSM-IV is formulated means there are over 2000 combinations of the 12 criteria that at the minimum threshold of six yield an autism diagnosis. DSM-5 proposes collapsing autism, Asperger's and PDD-NOS into a single " autism spectrum " category, combining and reducing criteria, vastly cutting the number of combinations that can lead to an autism diagnosis.” I wonder what the probability is based on a sample size of 10,000?  I only ask as I am taking a STATS class and this caught my attention.  Have a great day!
