| Abstract: | In this paper, we establish the relationships between (G) and , where (G) is the RBLUE of unknown parameter matrix B of he disturbing restricted growth curve model, and is of the ordinary model. Next, we define the distance measure D G . Which can be assessed the disturbing influence. Finally, me obtain the computationally convenient formula of D G . |
