Are you saying that the projections for the future should fit the past? I'm sorry.

Are you saying, that a model which does not fit past data will somehow correctly predict the future?

If you're talking about climate models, then they fit the observed historical data pretty well. lzw is wrong on that point.

Nope.

I'm saying that the models should fit the past data. I think I misunderstood lzw. :)
