Narjes, There's some examples of plotting distributions here (The library also has code for various GOF metrics): http://www.iro.umontreal.ca/~simardr/ssj/indexe.html Follow the `plot` link: http://simul.iro.umontreal.ca/ssj/doc/pdf/guidecharts.pdf Cheers, - Ole On 06/19/2015 04:22 AM,

Hi, I have a few questions regarding the implementation of the quadratic problem in the org.apache.commons.math.optimization.general.LevenbergMarquardtOptimizerTest. I assume the quadratic is defined as: f(x) = a*x^2 + b*x + c This is the implementation of the jacobian function:

I'll start documenting as I'm going along. Once I have a working draft I'll post it. I just learned how to spell Levenberg Marquardt a few days ago, so I'll probably need some help filling in blanks. Hope to have a rough draft soon. Cheers, - Ole On 01/31/2011 10:06 AM, Phil Steitz wrote:

It's a pretty unique case I agree. Long story, but I basically have the start of what is a normal distribution (Sometimes I get to the top of the bell and sometimes I get a 1/3 of the way). So I'd like to find the best fit mean and variance for the set of points. I'm reading up on numerical

I would try running as root to make sure it's a directory ownership/permission issue. If it runs fine as root, I would download and untar a fresh instance of tomcat (To make sure that Tomcat can read all files it created during the first boot - I think only log files and the pid). Rebuild

Gunnar, My understanding is that if you launch Tomcat fresh (Never been started before) it will create catalina.out and the pid-file, and since it's running at a non-root user (Say user tomcat), user tomcat will own the pid and the catalina.out file, as well as any other files created at
