DISTINGUISHING THE NOTABLITY OF THE AFFECTING FACTORS OF THE CRUSTAL MOVEMENTS

Liu quanwei (Taiyuan University of Technology,Taiyuan 033024) (Now Address:The University of Calgary,Canada)  
Making model of crust of movement we need consider the effect of various factors. To do so we must distinguish the notablity of affecting factors. The distinguishing method of cassical variance analysis by the adjustment of LS requires that affecting factors must be independent. But the actual surveying data are often dependent. This paper puts forward the theory of weighted variance analysis,and corresponding formulas are derived. Finally,we discuss its application,and a practical example is presented to demonstrate its application on vertical crustal movements.
