This workspace contains the functions in appendix 3.9 of Design of Observational Studies
These functions illustrate the exact sensitivity calculations.
They are appropriate without ties.
With ties, use the large sample approximation
The large sample approximation is fine for most practical work.
Exact calculations using the FFT as in appendix 3.9 are of theoretical interest.
Software comes with no guarantees of any kind.
