check_marker_binout: Checks of diagnosis scenarios

In sMSROC: Assessment of Diagnostic and Prognostic Markers

Checks of diagnosis scenarios

Description

Checks the consistency of the parameters entered for diagnosis scenarios.

Usage

check_marker_binout(marker, status, 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 a mandatory parameter in diagnosis scenarios.
probs	vector containing the probabilities corresponding to the predictive model when it has been externally computed. Obviosly, 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 ouput is a list with the following components:

marker	vector containing the biomarker values.
outcome	vector with the condition of the subjects as positive or negative.
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.
controls	number of negative subjects.
cases	number of negative subjects.
misout	number of subjects whose outcome value is not known.
message	table containing the warning messages generated during the execution of the function.
