Antithetic

Key Antithetic in Model[Simulation] refers to a boolean that controls whether the antithetic variate technique is used during the construction of the state values from the generated random numbers.
Set TRUE to apply this technique.
Set FALSE to NOT apply it.

This technique should be avoided when the Box Mulleris used because the latter random generator method constructs a random number by mixing a pair of consecutively generated random numbers.
