Detailed Description

compound-forward structure

Tests

*

the correctness of the curve is tested by reproducing the input data.

*

the correctness of the curve is tested by checking the consistency between returned rates and swaps priced on the curve.

Bug

swap rates are not reproduced exactly when using indexed coupons. Apparently, some assumption about the swap fixings is hard-coded into the bootstrapping algorithm.

Member Function Documentation

Rate zeroYieldImpl (Time t) const [protected, virtual]

Returns the zero yield rate for the given date calculating it from the instantaneous forward rate.

Warning

This is just a default, highly inefficient and possibly wildly inaccurate implementation. Derived classes should implement their own zeroYield method.

Reimplemented from ForwardRateStructure.

DiscountFactor discountImpl (Time t) const [protected, virtual]

Returns the discount factor for the given date calculating it from the instantaneous forward rate.

Reimplemented from ForwardRateStructure.
