Groeneboom and Hendrickx semiparametric binary response estimator (scalar case) score estimator based on NPMLE avoids any smoothing proposed by Groneboom and Hendrickx (2018).
GH.se(bstar, X, y, eps = 0.001, hc = 2)
A list with components:
evaluation of a score function at parameter value
estimated standard error
sindex single index linear predictor
parameter vector (fix last entry as a known number, usually 1 or -1, for normalization)
design matrix
binary response vector
trimming tolerance parameter
kernel bandwidth (used for the standard error estimation)
