Toleranceable .param

I have .model statements with a few of its parameters defined using an expression. For example, the RE model parameter of a BJT is RE={AV/gm}. AV and gm are defined using the .param statement. Is there a way to apply tolerances to AV and gm so that during a Monte Carlo the RE model parameter is a function of the toleranced AV and gm? As far as I can tell, there is no way to tolerance .param's. Other simulators allow toleranced params.

You have an option to define the tolerance for RE which can be defined as RE= (value) DEV 20%. With tolerance of AV and gm, you can try to derive the tolerance for RE and use it as DEV/GAUSS for Monte Carlo analysis.
