- Contemporary methods of geodetic observation adjustment are more often derived from (based on) M-estimation theory. This statement applies especially to robust methods of adjustment. This paper presents a new method of adjustment based on theory M-estimation with assymetric weight function. Such a function is obtained by multiplying original weights by assymetric attenuation function. The attenuation function consists of some, dependent on excess, terms of the Edgeworth series. The proposed method belongs to the class of robust estimations. However it also makes possible to apply asymmetry coefficient is an additional parameter (against the previously elaborated methods) that controls a robust adjustment.
