The implications of alternative allocation criteria in adaptive design for panel surveys
15 Feb 2017
We compare four methods for allocating sample members to one of two data collectionprotocols, in an adaptive survey design framework. The methods aim to optimise,respectively, response rate, R-indicator, coefficient of variation of participationpropensities, and effective sample size. The data collection protocols are CAPI single-modeand web-CAPI sequential mixed-mode. We find that two of the targetedallocations achieve a better response rate than single-mode CAPI at a lower cost. Allfour targeted designs out-perform both single-protocol designs in terms ofrepresentativity and effective sample size. For all but the smallest sample sizes, theadaptive designs bring modest cost savings relative to CAPI-only.
