Abstract: In this article,we consider the standard linear regression model with aggregated dataT=A'Y. We discuss the influence of aggregated data on fitted values at certain point,and get the upper orr lower bound of the inluence.In addition,we establish the relations between the fit statistic and corre- lation cocfficient.
