Discordant harmonies in views of natural systems by The Sierra Club and others

Posted on 15 August 2021 by ecoquant

This essay was first publish at the blog of the Green Congregation Committee, First Parish in Needham, on the Parish Realm Web site and communications board. The views obviously are those only of its author, not of First Parish or … 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.''
