Is there a formal test determining whether a verb is stative? For example, the following predicate looks stative, but it's not:
It's Valentine's Day. I have the chocolate, but I'm still missing the flowers.
You either are missing the flowers, or you're not. Also, there is no action involved. There is no degree to which you can be missing the flowers. Does not that imply that the verb is stative? How does one account for such cases?
