We detail nonparametric identification results for respondent-driven sampling when sampling probabilities are assumed to be functions of network degree known to scale. We show that the conditions for consistency of the Volz-Heckathorn estimator are weaker than previously assumed.
当抽样概率被假定为已知呈比例缩放的网络度的函数时,我们详细阐述了应答驱动抽样的非参数识别结果。我们表明,沃尔兹 - 赫卡索恩估计量一致性的条件比先前假定的要弱。
