concordancefit {survival} | R Documentation |
This is the working routine behind the concordance
function. It
is not meant to be called by users, but is available for other packages
to use. Input arguments, for instance, are assumed to all be the
correct length and type, and missing values are not allowed: the calling
routine is responsible for these things.
concordancefit(y, x, strata, weights, ymin = NULL, ymax = NULL, timewt = c("n", "S", "S/G", "n/G", "n/G2", "I"), cluster, influence =0, ranks = FALSE, reverse = FALSE, timefix = TRUE)
y |
the response. It can be numeric, factor, or a Surv object |
x |
the predictor, a numeric vector |
strata |
optional numeric vector that stratifies the data |
weights |
options vector of case weights |
ymin, ymax |
restrict the comparison to response values in this range |
timewt |
the time weighting to be used |
cluster, influence,ranks, reverse, timefix |
