So all discussion of economic projections, and economic statistics, should be largely mathematical?<br /><br />If Adam looked outside of the blogs, at real peer-reviewed papers, he would find extensive maths-based discussions of climate models, and their projections. But all that stuff is too hard even for real blogs, let alone Curry's.<br /><br />Another possible answer is that the models already embody the maths. What is needed is to translate this into other terms. Unless Adam is starting a campaign to move all decision making into maths'world.William M.
