Usage

Value

An object of class c('clos'). The object is a list of

cLOS change in LOS
trans an object of class 'trans'
e.given.1 estimates E(LOS|X_s = intermediate event) for all observed transition times s, where X_s denotes the state by time s
e.given.0 estimates E(LOS|X_s = initial state) for all observed transition times s, where X_s denotes the state by time s
phi2 weighted average of the difference between phi2.case and phi2.control
phi2.case estimates E(LOS 1(X_LOS = discharge)|X_s = intermediate event)
phi2.control P(X_LOS = discharge|X_s = intermediate event) E(LOS|X_s = initial state)
phi3 weighted average of the difference between phi3.case and phi3.control
phi3.case estimates E(LOS 1(X_LOS = death)|X_s = intermediate event)
phi3.control P(X_LOS = death|X_s = intermediate event) E(LOS|X_s = initial state)
empty.1 event times with the group `intermediate, but no terminal event yet' being empty
empty.0 event times with the group `no intermediate or terminal event yet' being empty
weights weights for the weighted average
w.times time points corresponding to the weights
called how the function was called
patients total number of observed patients
patients.discharge number of patients being discharged
patients.death number of patients who die
patients.cens number of patients being censored, i. e. for whom neither discharge or death was observed
cases number of patients who experienced the IE
cases.discharge number of patients who experienced the IE being discharged
cases.death number of patients who experienced the IE and died
cases.cens number of patients who experienced the IE and were censored
