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
Member Function Documentation
Real density | ( | Real | m | ) | const [virtual] |
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.
