problem on version

[hardmann]

Dear Tom:

I have programed a couple of the codes of State space with DLM to deal with Extend kalman filter. When I update Winrats from V11.00c to V11.00d, my old codes cannot get right result that is normal under V11.00c.
My codes is not stable, which has different result under different version. I have always been using the Winrats. When V10 releasing, I found my result of old codes from V9.0 is slightly different from V10.

I have an idea that the sub-version can roll-back or select sub-version.
Because I use Winrats frequently and extensively, so I encounter a lot of problem. I know my problem is seldom and stranger. Please Tom give me help and recommandation

Best Regard
Hardmann

We haven't made any changes to the DLM instruction since version 10. You would have to post (or send to support@estima.com) a program and data which shows the issue.
