beta,
time,
delta,
z,
w_hat = rep(1, length(time)),
wt_rg = rep(1, length(time)),
score_only = TRUE
)
Arguments
- beta

- time
Numeric vector of event times.
- delta
Numeric vector of event indicators.
- z
Numeric vector of group indicators.
- w_hat
Numeric vector of weights.
- wt_rg
Numeric vector of rho-gamma weights.
- score_only
Logical; if TRUE, returns only the score.
Value
