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.
