| contents | Doubly robust estimators combine an inverse probability weighting estimator and a mass imputation estimator. Several doubly robust estimators for estimating the population mean (or prevalence) of an outcome have been proposed for integrating outcome and covariate data from a nonprobability survey with covariate data from an auxiliary probability survey. However, the question of how to combine a doubly robust estimate with a corresponding estimate based on outcome data from the auxiliary probability survey alone has only received limited attention. In this paper, we (i) review previously proposed doubly robust estimators, (ii) provide formulae for the variance of doubly robust estimators and the covariance between doubly robust and probability survey estimates, (iii) propose a framework for how to combine efficiently a doubly robust estimate from a nonprobability sample with an estimate based on the auxiliary probability sample alone, and (iv) provide formulae for the variance of such combined estimates. |
