Hi!
STAN does not support automated sensitity analysis.
But if your model has enough input parameter that unknown quantities can be calculated you can do it manually:
(1) Record the status quo (values of input parameter and result(s) of interest).
(2) Change one of the input parameter (absolute/relative) and have a look how much this change influences the result of the variable of interest (absolute/relative).
(3) Repeat (2) for all input parameter.
(4) Find those parameter whose changes have the biggest effect on the result (absolute/relative). They are the most sensitive.
