In most systems there usually is a mixture of categories used in some fixed rank fashion for all items. For example, first a deterministic approach is used. If it is not successful, then a hot deck approach is tried. This is followed by a model-based approach. If all these approaches fail, then a manual imputation occurs through a human review process.
