Making use of incomplete observations for regression in bivariate normal model. (English) Zbl 1099.62508

Summary: Two estimates of the regression coefficient in bivariate normal distributions are considered: the usual one based on a sample and a new one making use of additional observations of one of the variables. They are compared with respect to variance. The same is done for two regression lines. The conclusion is that the additional observations are worth using only when the sample is very small.
