Sample Size Calculations for Population Size Estimation Studies Using Multiplier Methods With Respondent-Driven Sampling Surveys

Sample Size Calculations for Population Size Estimation Studies Using Multiplier Methods With Respondent-Driven Sampling Surveys

Johnston et al. [4] suggest using the Delta method to estimate the variance of the PSE, which combines variance in P and variance in M. We assume that M, as a count of target population individuals on a roster or unique objects distributed to the target population, follows a Poisson distribution for which the mean and variance are equal to µM [8].  The variance of P depends on the sample size of the RDS survey.
