  • 摘要:

    In censuses as well as in various surveys, some respondents do not give answers to the stated questions. This, unavailability is a component of surveying. The problem arising from the sample unavailability is that the units selected to be included in the sample are, in fact, missing. Not only do these missing values cause less efficient estimates (due to the reduction in the sample size), but they also make impossible the use of standard statistical methods (which assume that there are no missing units). The multiple embedding method is a technique which replaces each missing or incomplete datum by two or more acceptable values drawn from the data distribution. It means that each lost value is replaced by m embedded values in the form of a vector.
