Multivariate regression estimates for finite populations
Annals of The Institute of Statistical Mathematics(1968)
摘要
The theory on regression estimate based on one auxiliary variable has been extended to that for more than one auxiliary variable.
It has been found that the multivariate regression estimate (MRE) is not unbiased in general. The form of the approximate
standard error of MRE is the same as that of simple regression estimate based on one auxiliary variable with the exception
that the multiple correlation coefficient replaces the total correlation coefficient in the expression. It has also been found
that the precision of MRE is non-decreasing, rather usually increasing as the number of auxiliary variables correlated with
the dependent variable increases, assuming sample size to be large compared to the number of auxiliary variables.
