Probability test on point position droping into error ellipse

PENG Zhen-zhong(School of Geodesy and Geomatics, Wuhan University, Wuhan 430072, China)  
In the general error testing, people usually perform it in one dimension and hardly extend to two dimensions or even more. The observed point(x, y) follows the two-dimensional normal distribution, can be extended to three dimensions. The simulant calculation shows that the method has more efficient than the one in one dimension. The key idea of testing is whether the point drops into the range of error ellipse under the given confident limit. If the testing value exceeds the given confident limit, the observedvalue of the point will be abandoned.
