D.index
(Package: survcomp) :
Function to compute the D index
Function to compute the D index for a risk prediction, i.e. an estimate of the log hazard ratio comparing two equal-sized prognostic groups. This is a natural measure of separation between two independent survival distributions under the proportional hazards assumption.

cindex.comp
(Package: survcomp) :
Function to compare two concordance indices
This function compares two concordance indices computed from the same data by using the function concordance.index. The statistical test is a Student t test for dependent samples.

concordance.index
(Package: survcomp) :
Function to compute the concordance index for survival or binary class prediction
Function to compute the concordance index for a risk prediction, i.e. the probability that, for a pair of randomly chosen comparable samples, the sample with the higher risk prediction will experience an event before the other sample or belongs to a higher binary class.

dindex.comp
(Package: survcomp) :
Function to compare two D indices
This function compares two D indices from their betas and standard errors as computed by a Cox model for instance. The statistical test is a Student t test for dependent samples. The two D indices must be computed using the D.index function from the same survival data.
