The concept of YRestimation presented in (6] is generalised in case of dependent observations. The basis of the method is usage of reinforcement matrix which guarantees the robustness of the estimate. The reinforcement matrix which is closely connected with the weight function of M-estimation, gives a possibility to perform robust adjustment. Thus such a method is also presented. At last, an example is shown too.}, type={Article}, title={Robust estimation of variance coefficient (YR-estimation) for dependent observations}, URL={http://ochroma.man.poznan.pl/Content/121671/PDF-MASTER/4_GK_TOM_XLIX_ZESZYT_3_2000_Duchnowski_Odporna.pdf}, }
