change Parameters
A convenience method that will set any Double or Integer parameter to the supplied double value provided that the named random variable is available to be set, and it has the named parameter.
The inner map represents the parameters to change. Double values are coerced to Integer values by rounding up. If the key of the supplied map representing the random variable to change is not found, then no change occurs. If the parameter name is not found for the named random variable's parameters then no change occurs. In other words, the change "fails silently"
