I apologize in advance if I picked the wrong list to post this to. I have made an effort to find the answers to these questions on CRAN, but if they are there, I couldn't find them, and I was going to email the developer of StructTS directly but could not find who that is. I have 2 interrelated questions about StructTS 1. Where can I obtain the source code for StructTS if I wanted to produce a similar function with an extended capability? 2. Would the person who developed StructTS have any interest in adding the ability to include an AR term and/or a stochastic cycle?

Hi Roy Have you managed to find the source code for StructTS after all? I am looking for it as well but cant seem to find it, thanks Chris Roy Mendelssohn wrote:> > I apologize in advance if I picked the wrong list to post this to.

Hey Roy ... it's been awhile. We have an example of structural equation modeling in our text in section 6.5. There's also an example and the R code for the example is here: http://www.stat.pitt.edu/stoffer/tsa2/chap6.htm Scroll down to "Code to do Example 6.10 via BFGS" The scripts are written from scratch so it's easy to see what's go on (I hope) and you can alter the code to suit your needs. Feel free to email me if you want to discuss the problem. Roy Mendelssohn wrote:> > I apologize in advance if I picked the wrong list to post this to.
