Cross Validation for Sequential BATTing
1 2 3 4 |
y |
data frame containing the response |
x |
data frame containing the predictors |
censor.vec |
vector giving the censor status (only for TTE data , censor=0,event=1) : default = NULL |
trt.vec |
vector containing values of treatment variable ( for predictive signature). Set trt.vec to NULL for prognostic signature. |
trtref |
code for treatment arm. |
type |
data type. "c" - continuous , "b" - binary, "s" - time to event : default = "c". |
n.boot |
number of bootstraps in BATTing step. |
des.res |
the desired response. "larger": prefer larger response. "smaller": prefer smaller response |
class.wt |
vector of length 2 used to weight the accuracy score , useful when there is class imbalance in binary data defaults to c(1,1) |
min.sigp.prcnt |
desired proportion of signature positive group size for a given cutoff. |
pre.filter |
NULL, no prefiltering conducted;"opt", optimized number of predictors selected; An integer: min(opt, integer) of predictors selected. |
filter.method |
NULL, no prefiltering, "univariate", univaraite filtering; "glmnet", glmnet filtering, "unicart": univariate rpart filtering for prognostic case. |
k.fold |
number of folds for CV. |
cv.iter |
algorithm terminates after cv.iter successful iterations of cross-validation. |
max.iter |
total number of iterations allowed (including unsuccessful ones). |
a list containing with following entries:
stats.summary |
Summary of performance statistics. |
pred.classes |
Data frame containing the predictive clases (TRUE/FALSE) for each iteration. |
folds |
Data frame containing the fold indices (index of the fold for each row) for each iteration. |
sig.list |
List of length cv.iter * k.fold containing the signature generated at each of the k folds, for all iterations. |
error.log |
List of any error messages that are returned at an iteration. |
interplot |
Treatment*subgroup interaction plot for predictive case |
