Does worst case analysis work with model parameters?

[honcho]

The worst case analysis does not seem tow work with model parameters. I performed a worst case analysis on a simple one transistor amplifier stage. It gives correct answers for resistor tolerances, but for the transistor model parameters it never changes them. I did the same with a diode in the circuit and entered tolerances for the diode parameters and it never used the tolerances.

I agree, this doesn't appear to be working in the simple test case I have created.  I keep receiving an error message:

    <model_name> <parameter> unchanged from <orig_value> 

Can you attach your circuit?

That's the same message I get. See attached circuit.
