DLM uses more information than BENDY. While BENDY uses Y[i,1] and Y[i,t*] for dynamic prediction, DLM includes data Y[i,1:t*] which contains all the known history before time t* for a subject i. The DLM model fit is done at each point t* + j.

data |
A matrix of values with each row representing an individual and each column representing measurements at each time point (e.g. column 1 is time point 1, etc.). Measurements are assumed to be taken at the same time intervals for every participant. |
time |
A vector of times. This equal the number of columts in the matrix provided (0 through 15 months for the example dataset). |
hist.lngth |
The length of known history for the observed process. We use leave one-curve out cross validation for prediction (hist.lgth is 7 for the example dataset). |
A matrix of predictions with rows representing each individual and columts representing predictions for each time point.
