Statistical estimation of a growth-fragmentation model observed on a genealogical tree
Marie Doumic, Marc Hoffmann, Nathalie Krell +1
We model the growth of a cell population by a piecewise deterministic Markov branching tree. Each cell splits into two offsprings at a division rate that depends on its size…
Blockwise SVD with error in the operator and application to blind deconvolution
S. Delattre, M. Hoffmann, D. Picard +1
We consider linear inverse problems in a nonparametric statistical framework. Both the signal and the operator are unknown and subject to error measurements. We establish minimax r…
On adaptive inference and confidence bands
Marc Hoffmann, Richard Nickl
The problem of existence of adaptive confidence bands for an unknown density that belongs to a nested scale of Hölder classes over or is considered. Wherea…
Scaling limits for Hawkes processes and application to financial statistics
Emmanuel Bacry, Sylvain Delattre, Marc Hoffmann +1
We prove a law of large numbers and a functional central limit theorem for multivariate Hawkes processes observed over a time interval in the limit .…
