Internal function to process a list of observation snapshots
into the matrix format required by the truncation Stan model.
Usage
prepare_truncation_obs(data, trunc_max)
Arguments
- data
A list of <data.frame>s each containing date and confirm
columns. Each data set should be a snapshot of reported data.
- trunc_max
Integer, the maximum truncation delay to consider.
Value
A list containing:
obs: Matrix of observations (time x datasets)
obs_dist: Vector of NA counts per dataset (used to determine truncation)
t: Number of time points
obs_sets: Number of observation datasets
dirty_obs: The processed data.tables (ordered by nrow)
