check_marker_timerc: Check of prognosis scenarios under right censorship

In sMSROC: Assessment of Diagnostic and Prognostic Markers

Check of prognosis scenarios under right censorship

Description

Checks the consistency of the parameters entered for prognosis scenarios under right censorship.

Usage

check_marker_timerc(marker, status, observed.time, time, probs, sd.probs)

Arguments

marker	vector with the biomarker values. It is a mandatory parameter.
status	numeric response vector. Only two values will be taken into account. The highest one is assumed to stand for the subjects having the event under study. The lowest value, for those who do not. Any other value will not be considered. It is mandatory in prognosis scenarios and right censorship.
observed.time	vector with the observed times for each subject. These values can be the event times or the censoring times. It is mandatory when dealing with time-dependent outcomes under right censorship.
time	point of time at which the sMS ROC curve estimator will be computed. It is a mandatory parameter. The default value is 1.
probs	vector containing the probabilities corresponding to the predictive model when it has been externally computed. Only values between [0,1] are admissible.
sd.probs	vector with the standard deviations of the probabilities entered in probs. It is an optional parameter.

Value

The function returns a list with the following components:

marker	vector containing the biomarker values.
status	response vector.
observed.time	vector containing the observed time. Recall event/censoring time.
probs	vector with the probabilities corresponding to the predictive model.
sd.probs	vector containing the standard deviations of the predictive model if they have been manually entered.
outcome	vector with the condition of the subjects at the time given in time as positive, negative or unknown.
controls	number of negative subjects.
cases	number of positive subjects.
misout	number of unknown subjects.
message	table containing the warning messages generated during the execution of the function.
