One-factor Gaussian Copula.
The copula model
is specified here by setting the desnity function for all variables, and also
to the standard normal distribution
Density function of M.
Derived classes must override this method and ensure zero mean and unit variance.
Implements OneFactorCopula.
Real cumulativeZ | ( | Real | z | ) | const [virtual] |
Cumulative distribution of Z.
Derived classes must override this method and ensure zero mean and unit variance.
Implements OneFactorCopula.
Real cumulativeY | ( | Real | y | ) | const [virtual] |
overrides the base class implementation based on table data
Reimplemented from OneFactorCopula.
Real inverseCumulativeY | ( | Real | p | ) | const [virtual] |
overrides the base class implementation based on table data
Reimplemented from OneFactorCopula.
