The state of the science: “Heißzeit” … where we are heading.

Posted on 16 August 2019 by ecoquant

If you do not change direction, you may end up where you are heading. ― Lao Tzu Professor Johan Rockström, again. Yeah, and that makes me feel, this way … (Ricardo Maranhão with Indiara Sfair) (Indiara Sfair and Joe Flip) … Continue reading →

    I have used dlm almost exclusively, except when extreme efficiency was required. Since Jouni Helske's KFAS was rewritten, though, I'm increasingly drawn to it, because the noise sources it supports are more diverse than dlm's. KFAS uses the notation and approaches of Durbin, Koopman, and Harvey.

    ``The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil (or at least most of it) in programming.''
