2010 May 29: Searching this blog.
The command-F search is limited to a page of 10 posts at a time… and because the posts have been split, it does not search the non-dislayed portions of posts, or other pages.

I have added a “Search this blog” widget, over on the right. It really seems to search the entire blog. It will pull up multiple pages of posts containing the search string — but it won’t show you where the string occurs.

But now you can use command-F on the pages the widget selected!

I tested this by searching for “orbit” with the widget… it pulled up two pages of displayed posts, and the bibliography, too — and command-F worked within each page.

Odd… I wasn’t paying close enough attention. The blog search does select every post or other page containing the search string, but it does not expand the posts. So we have to do that ourselves. OTOH, at least we are guaranteed that each post selected does in fact contain the search string. That is an improvement.

In summary, searching the blog is a 2-step 3-step process. First, use the box on the right to select all posts containing the search string; second, expand a selected post; third, use command-F to actually locate the search string within that post.

(Of course, command-F will show locations in the opening portions of each post, but there may be more in the hidden portions.)

6 aug 2008: Finding books by date of entry or latest edit. If you want to find, for example, the books I entered or edited in June 2008, do a search on “jun 2008”. I have made sure that all the months are 3 letters, and all the years are 4 digits, and if there’s a day, it precedes the month. If you want to find all the entries I touched in 2008, search on “2008]”, where the “]” will skip over dates of publication. I am, in fact, planning a mass edit of the entries, and you should be able to find all the changed entries by searching on DD MMM.

older posts
if you click on the “math PCA” category, you get a page on which the earliest post is dated Feb 11; it is one of the Jolliffe posts, but not the first one. where are the rest? there is a link at the bottom of that page, “older posts”, and it will give you all the rest of the posts in that category. I suspect that I have no more than 10 posts per page, and that eventually there will more multiple pages of earler posts. I’ll let you know.


if you see any of those yellow and red signs (excluding that one, of course), please try again in a little while. the chances are very high that wordpress is being flaky. “it’s not my fault.”

i do make mistakes, and there are typos in these posts, but that image is real hard to miss; it’s exactly what i see when i preview an equation that isn’t acceptable latex to wordpress. i promise you: there aren’t any of those left when i publish a post. that much i do get right.

please keep coming back despite some technical glitches.

on a mac, apple-F opens up a search box. it is limited to the current page, but you can change the page. on windows, control-F opens a search box. the exact form and location depends on the browser.

the bibliography is now current.

note that you can search through it.

    This is a very nice site. I have been using Mathematica’s NonlinearModelFit function and ordering the results according to their AIC & BIC scores. I wanted to calculate my own AIC/BIC values AND compare them to those produced by Mathematica.

    I didn’t know what they had done. Your page was a big help in clearing that up for me. I might reference it in a paper unless you know if those formulae are published somewhere within Wolfram’s pages?

    Hi JEP,

    I’m glad to have been of help.

    My source for the AIC formula was McQuarrie & Tsai, “Regression and Time Series Model Selection”, 981-02-3242-X, p. 21. I modified their SIC (BIC) formula on p. 23 by using (k+1) where they used k.

    Then i confirmed that my two equations matched Mathematica’s answers. Mathematica’s brief discussion of AIC and BIC can be found in the tutorial for statistical model analysis, but I do not recall seeing the actual equations anywhere on Wolfram.

    BTW, I’m going to copy this comment to the “selection criteria” post.

    If you’ve done office parties or corporate work, make sure to mention that as well.
