Add more tuning steps

1

Hi,

I initially used 10,000 tuning steps for my model in pm. sample() and found that it was not enough. I want to add more tuning steps instead of restarting the sampling procedure entirely since it’s too time-consuming. How can I do that?

Needing that many steps is a red flag that there is something wrong with your model.

You should investigate that first before considering increasing the number of steps even more.

Thanks for the reply! I will try to simplify the model. It may be because the model has lots of random noise. I still wonder if I can add more tuning steps instead of restarting the sampling procedure entirely.

There are lots of useful things happening during tuning. But if you need to extend the tuning phase dramatically, it suggests that part of what is happening during tuning is that the sampler is trying to compensate for model issues.
