copy_reference: Create a copy reference 'ImputeMechanism' object
In scientific-computing-solutions/dejaVu: Multiple Imputation for Recurrent Events

Description Usage Value See Also Examples

Missing counts for subjects in both arms are imputed by assuming the rate before and dropout are both equal to the control (reference) estimated rate. This corresponds to what is usually termed the copy reference assumption.
