The presence of aberrant observations (i.e. outliers) in cell lineage data is quite common. As such, it is desirable to have an outlier-resistant estimation procedure as an alternative to least squares estimation (maximum likelihood estimation under normality). In this work, we consider rankbased estimates of the parameters of a first order bifurcating autoregressive [BAR(1)] model. The BAR(1) model was proposed by Cowan and Staudte (1986) for cell lineage data. In it, each line of descendents follows a first order autoregressive [AR(1)] model and allows sister cells from the same mother to be correlated. Real examples and a simulation study are …

The goal of the present work is to observe x-rays from oxygen for the purpose of investigating resonant-transfer and excitation (RTE) [1], and projectile and target x-ray emission resulting from inner-shell capture. Projectile energies in the range 5-25 MeV will be examined to investigate RTE for heavy targets [2,3].
