Calculates initial optimal bandwidth with respect to mean squared error using K-fold cross-validation.
optimize.mse.BW(data, t0,tau,h.grid=seq(.01,2,length=50), folds=3, reps=2)
Selected bandwidth.
n by 5 matrix. A data matrix where the first column is XL = min(TL, C) where TL is the time of the long term event, C is the censoring time, and the second column is DL =1*(TL<C), the third column is XS = min(TS, C) where TS is the time of the short term event, C is the censoring time, the fourth column is DS =1*(TS<C), and the fifth column is the covariate. These are the data used to calculate the estimated probability.
the landmark time.
the residual survival time of interest.
The grid of possible bandwidths that the user would like the function to search through. Default is h.grid = seq(.01,2,length=50).
Number of folds wanted for K-fold cross-validation. Default is 3.
Number of repitions wanted of K-fold cross-validation. Default is 2.
