In ebenmichael/balancer: Matrix constraints for covariate balance

Re-weight control sub-groups to treated sub-group means

Description

Re-weight control sub-groups to treated sub-group means

Usage

survival_qp(
  B_X,
  trt,
  times,
  events,
  t,
  lambda = 0,
  lowlim = 0,
  uplim = NULL,
  verbose = TRUE,
  eps_abs = 1e-05,
  eps_rel = 1e-05,
  ...
)

Arguments

B_X	n x k basis matrix of covariates
trt	Vector of treatment assignments
times	Vector of event/censoring times (see events for if event or censoring time)
events	Vector of boolean censoring indicators (whether individual was censored)
t	Time
lambda	Regularization hyperparameter, default 0
lowlim	Lower limit on weights, default 1
uplim	Upper limit on weights, default NULL
verbose	Whether to show messages, default T
eps_abs	Absolute error tolerance for solver
eps_rel	Relative error tolerance for solver
...	Extra arguments for osqp solver

Value

• weightsEstimated weights as a length n vector

• imbalance0Imbalance in covariates for control in vector

• (imbalance1)Imbalance in covariates for treated in vector
