New Algorithms for -Estimation of Multivariate Scatter and Location
Lutz Duembgen, Klaus Nordhausen, Heike Schuhmacher
We present new algorithms for -estimators of multivariate scatter and location and for symmetrized -estimators of multivariate scatter. The new algorithms are considerably fa…
M-Functionals of Multivariate Scatter
Lutz Duembgen, Markus Pauly, Thomas Schweizer
This survey provides a self-contained account of -estimation of multivariate scatter. In particular, we present new proofs for existence of the underlying -functionals and di…
Maximum-Likelihood Estimation of a Log-Concave Density based on Censored Data
Lutz Duembgen, Kaspar Rufibach, Dominic Schuhmacher
We consider nonparametric maximum-likelihood estimation of a log-concave density in case of interval-censored, right-censored and binned data. We allow for the possibility of a sub…
Inference on a Distribution Function from Ranked Set Samples
Lutz Duembgen, Ehsan Zamanzade
Consider independent observations , , \ldots, with random or fixed ranks , while conditional on , the random va…
