Talk:Mean-preserving spread

" If B is a mean-preserving spread of A, then B is second-order stochastically dominant over A; and the converse holds if A and B have equal means." Or " If B is a mean-preserving spread of A, then A is second-order stochastically dominant over B; and the converse holds if A and B have equal means."??


 * It was correct as written: If B is a mean-preserving spread of A, then A is second-order stochastically dominant over B; and the converse holds if A and B have equal means. Duoduoduo (talk) 01:01, 4 February 2011 (UTC)
