Abstract
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.
