Calculate the probability of a TimeSeriesModel?

I have generated a model by using the TimeSeriesModel. How I can calculate the probability of something happen one day by using this model?

Can you express the “something happen one day” as event, and that event in form of a random variable? Or are you talking of a random process?

Good luck. Also that your post doesn’t get deleted.

Include details of your model and code. Your post is too vague.
