1:4 matching for Proc SurveySelect

Below reference is the following paper: Simplified Matched Case-Control
Sampling PROC SURVEYSELECT
(http://www2.sas.com/proceedings/sugi29/209-29.pdf)

Now, I want to create a matched dataset just as they do in this paper
based on a number of matching criteria but I want the match to be 1
case to 4 controls rather than the 1 to 1 match that they did in this
paper.  I assume this is fairly easy to do but I am not sure where to
start.

Thanks in advance,

Alex

[wxPython 2.5.3.1] How can I find where an exception is raised from?
[wxPython 2.5.3.1] How can I find where an exception is raised from? I often receive unhandled exceptions when clicking on widgets like wx.TextCtrl e.g.. The reason is probably that they are updated in timer events (they have to display current values) at the same time I click on them. What can I do to investigate this in detail? The Unhandled Excpetion Dialog w/o any traceback and only offering Abort/Retry/Ignore is of no help (seems coming from deep down in C++ -wxWidgets). I have already overridden wxApp::OnFatalException() and wxApp::OnExceptionInMainLoop(). But they don't ...

1 - 1, 1 -1, 1-1, 1
Hi, I have a question regarding lexical analysis. I recently came across a bug in our lexical analyser in phc (www.phpcompiler.org), that I am unsure how to solve. This is the problem: our current definition for integer constant looks something like INT ([1-9][0-9]*)|0 In particular, note that it does not allow for an (optional) "+" or "-" at the start of the integer. This means that the strings "1 - 1", "1 -1" and "1-1" all generate the same sequence of three tokens INT(1), OP(-), INT(1), for which the syntax analyser generates the subtr...

firestarter on FC3/kernel-2.6.9-1.681
I upgraded to Fedora Core 3 and immediately updated the kernel to 2.6.9-1.681. It seemed to work and I removed 2.6.9-1.667. Now I've discovered that firestarter doesn't work. I've tried old and new versions and building from source. I consistently get an error message telling me that "A proper configuration for Firestarter was not found." Can anybody explain what is wrong? Can anybody confirm that firestarter does work with either of these kernels (and fully updated FC3)? I should be able to find an older kernel somewhere if it's the new kernel that is the problem. B...

syswrite changes from 1.8 to 1.9
Hi guys, I have a ruby script which is scraping a website with Hpricot. I am creating an xml and an sql file from data scraped. it was working well under 1.8, but I have upgraded to 1.9 (because of character encoding), but now the script writes '["' in front of every string, and the '\n' gets written as a '\n' and not as a new line. I am using double quotes when assigning the string to a variable. What should I change? regards Tom -- Posted via http://www.ruby-forum.com/.

Generate randomly between -1 and 1
Hi everyone, Just wondering if anyone has an idea how I can generate -1 and 1 randomly. I basically wanted a formula of the form z = y ± x where x is added or took away with equal probability. my idea was to do z = y + r.*x then make r be -1 and 1 at random. Also, I need to plot this function. Will there be further problems?
