The Odds, Continually Updated 2014-09-29T04:00:00Z Before considering what other researchers should or shouldn’t do to clarify things, we need to do some ‘Bayesian’ thinking. From the shadows to the spotlight to the dustbin - the rise and fall of GFAJ-1 2011-06-16T13:15:02.533Z And by using a statistical technique called Bayesian analysis it is possible to combine such disparate pieces of information to produce a consolidated estimate that is more accurate than any of its components.
