Description Usage Arguments Value
Computational workhorse function. Maximizes the value of hatmu among all Hajek ratio estimators that satisfy the following properties: - The ratio of the sampling weights gamma is bounded - The resulting CDF is symmetric to within tolerance delta.

sampling.ratio |
The bound on the sampling ratio. |
center |
The center of symmetry. |
delta |
The tolerance parameter. |
Xcdf.weighted A weighted version of Xcdf that maximizes hatmu
