Whats the difference between ascription and fusion?
They are generally based on very similar techniques, but ascription usually applies to procedures employed within a study and fusion takes place across separate studies. Another difference is that, with ascription, a relatively small portion of responses are imputed or modeled, while 100% of responses are imputed with fusion. Consequently, there is a much greater likelihood of error with fusion than with ascription.
