Abstract

Pilot investigations and repeated studies often provide some useful information which can be utilized for the estimation of coefficients in a linear regression model when some observations on the study variable are missing. A suitable framework for this purpose is described and several unbiased estimators for the coefficient vectors are presented. Their efficiency properties are analyzed and a comparison is made.
