imputation_singles() grouped by a single subjid IDA collection of imputation_singles() grouped by a single subjid ID
imputation_list_single(imputations, D = 1)a list of imputation_single() objects ordered so that repetitions
are grouped sequentially
the number of repetitions that were performed which determines how many columns the imputation matrix should have
This is a constructor function to create a imputation_list_single object
which contains a matrix of imputation_single() objects grouped by a single id. The matrix
is split so that it has D columns (i.e. for non-bmlmi methods this will always be 1)
The id attribute is determined by extracting the id attribute from the contributing
imputation_single() objects. An error is throw if multiple id are detected
