Two-stage Sampling on Additive Model for Quantitative Sensitive Question Survey and Its Application

摘要

Objective To explore scienti?c sampling methods and corresponding formulas for quantitative sensitive question survey on two-stage random sampling. To provide scienti?c data for the prevention and control of high risk AIDS population in Beijing. Methods Additive model for quantitative sensitive question survey, two-stage random sampling, properties of variance and mean were used. Results Formulas for the esti?mation of the population proportions and its variance on additive model for quantitative sensitive question survey were deduced. The survey methods and formulas were employed successfully in the survey of the age of the ?rst time when MSM having sex with men and the result was 21.9747. Conclusion The methods and corresponding formulas for two-stage sampling on additive model for quantitative sensitive question survey are feasible.
