In the researches of family-based cluster sampling, the observations of interested variable of the same family members are correlated.
在以家庭为单位的整群抽样调查研究中,由于家庭成员的观测指标间存在一定的内部相关性(intra-family correlation),不符合独立性的假设,若用传统的基于独立性假设的有关方法直接进行分析,即忽略了观察对象在不同家庭的内部相关性,误将其看作独立样本,得到的各参数估计值的有效性和其他统计特性均会受到影响,甚至会给统计推断结论带来偏倚。
