I want to make a time-dependent distribution where one of the time periods is based on a combination distribution i've made.
For example, take A1 as a fixed distribution of -1.3
Take A2 as a lognormal distribution with parameters (170,310)
Then I've formed a combination distribution of the two (called A).
When I go to make a time-dependent distribution, I am able to use A1 and A2, but A is not on the list! Why? Is there some way of doing this?
Working on a project with deadline this weekend, please help if you can!!!
