Calculate risk set and event counts at time points

Description

Calculates risk set and event counts for a group at specified time points, with variance estimation.

Usage

calculate_risk_event_counts(U, D, W, at_points, draws = 0, seedstart = 816951)

Arguments

U	Numeric vector of times for group.
D	Numeric vector of event indicators for group.
W	Numeric vector of weights for group.
at_points	Numeric vector of time points.
draws	Number of draws for variance estimation (default 0).
seedstart	Random seed for draws (default 816951).

Value

List with ybar (risk set counts), nbar (event counts), sig2w_multiplier (variance term).
