WebJun 5, 2012 · I know that, in survival analysis, the concordance index (c-index) can be used to measure how well a ranking list is w.r.t survival times of subjects (F. E. Harrell, 1996, section 5.5). That is, if subjects with higher survival times get higher scores from the model, the c-index of the model will be large. WebComputes Harrel's C index for predictions from a "coxnet" object. Cindex (pred, y, weights = rep (1, nrow (y))) Arguments pred. Predictions from a "coxnet" object. y. a survival response object - a matrix with two columns "time" and "status"; see documentation for "glmnet" weights.

WebMay 27, 2024 · The C-index (= 0.5 + (D xy /2)) is just the fraction of pairs of comparable cases for which the predicted and observed order of events agrees. For a single model that's a useful measure of the ability to discriminate among cases, but it doesn't evaluate overall model calibration, "the ability of the model to make unbiased estimates of outcome." WebC is a general-purpose programming language, developed in 1972, and still quite popular.
