estimator(x, w = NULL, y = NULL, z = NULL, dens = NULL)"DynTxRegime"."IQLearnFS" or "IQLearnSS"."IQLearnFS" or "IQLearnSS"."IQLearnFS" or "IQLearnSS"."character" indicating density approximation. Must
be one of {'nonpar', 'norm'}.For the IQ-learning algorithm, additional inputs
are required to obtain the estimated value of the
first-stage treatment. Function estimator() required
inputs w, x, y, and z are the three first-stage
and single second-stage objects (in no specific order).
For all other methods, no information beyond the value object returned by the method is needed.
