WebThe models and (9) are estimated with a local-linear kernel smoother using the quartic kernel and the optimal bandwidth is chosen by cross-validation, that is, by maximizing the R V 2 given by and . Moreover, it should be kept in mind that the nonparametric method can estimate linear functions without any bias, given that we apply a local-linear smoother. Websample. Times are in radians. It may return a matrix of NAs if smooth = TRUE and bandwidth estimation fails. Function bootEst with type = "all" returns a numeric matrix with three columns, one for each estimator of overlap, otherwise a vector of bootstrap estimates.

The function π is the propensity score and is known in a randomized trial setting, which we assume is the case for this paper, but needs to be estimated in a non-randomized, observational study setting.
