TY - GEN TI - On the Breakdown Properties of Two M-Functionals of Scatter N2 - The breakdown properties of two M-functionals of scatter are treated. The first functional is Tyler's (1987) M-functional for distributions onq-dimensional space, centered at zero. The second functional is Tyler's M-functional applied to symmetrized distributions. While deriving explicitformulas for the breakdown points, we also investigate the causes of breakdownin detail.
