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.

WebJan 10, 2024 · Arrays in C are indexed starting at 0, as opposed to starting at 1. The first element of the array above is point[0]. The index to the last value in the array is the array size minus one. In the example above the subscripts run from 0 through 5. C does not guarantee bounds checking on array accesses. WebIt can be computed with the following formula : C-index = ∑i,j1T jηi ⋅ δj ∑i,j1T j η i ⋅ δ j ∑ i, j 1 T j < T i ⋅ δ j. with: ηi η i, the risk …
WebJul 10, 2015 · Show the UI with index 1, use index 0 in code. That said, I worked with audio devices like this and used index 1 for the channels and designed the code never to use "Index" or indexers to help avoid frustration. Some programmers still complained, so we changed it. Then other programmers complained. Just pick one and stick with it. WebJul 15, 2024 · To get a feeling of the baseline performance I generated some random prediction for the validation data. This random prediction already yields a pretty high C-Index > 0.7. My feeling is, that this stems from the fact that the data contains only few failure cases. Because survival chances are pretty high and a lot of data points are right censored.
