| Abstract: | Fusion is the linking of two survey datasets by pairing up similar respondents and joining their data records, in order to be able to cross-analyse outputs from one survey with those from the other. Depending on the particular method of fusion used, the size of the fused dataset may be the same as one of the surveys or different to both. An issue still unresolved is the effective sample size of the fused dataset. That is, what should be the size of a hypothetical single-source sample that would deliver equal variances and standard errors to the fusion? This paper addresses this question and provides three main findings. |
