Monte Carlo analysis takes into account different model parameters (Bv, Is...)?

While doing the Monte Carlo analysis, is there a way to know if model parameters such as saturation current, reverse breakdown voltage and much more, are being taken into account? Or does it only affect to established tolerances in R,L,C...?

    The Monte Carlo analysis calculates the circuit response to changes in part values by randomly varying all of the model parameters for which a tolerance is specified. This provides statistical data on the impact of a device parameter’s variance.
    So for example if you have defined tolerance on saturation current of a transistor (Is) it will vary its value within the defined range randomly while performing analysis.

    Okay, thanks. But how would you define tolerance for model parameters? I haven't found a way to do it yet.

    This is what i tried

    And same can be seen in the mcp file as below after running MC

    Regards,
