Initializes the specification of a CDE estimator based on an inverse probability weighting approach.
cde_ipw(hajek = TRUE, trim = c(0.01, 0.99))If TRUE, normalized weights will be used as in the
Hajek estimator. If FALSE, traditional IPW weights will be used.
A vector of length 2 indicating what quantiles of the
propensity scores should be trimmed. By default this is c(0.01, 0.99) meaning that the top and bottom 1% of propensity scores are
trunctated to these quantiles. If NULL, no trimming occurs.
