Another view of sequential sampling in the birth process with immigration
Poly H. da Silva, Arash Jamshidpey, Simon Tavaré
Models of counts-of-counts data have been extensively used in the biological sciences, for example in cancer, population genetics, sampling theory and ecology. In this paper we exp…
Random derangements and the Ewens Sampling Formula
Poly H. da Silva, Arash Jamshidpey, Simon Tavaré
We study derangements of under the Ewens distribution with parameter . We give the moments and marginal distributions of the cycle counts, the number of cycle…
Partial geodesics on symmetric groups endowed with breakpoint distance
Poly H. da Silva, Arash Jamshidpey, David Sankoff
The notion of partial geodesic was introduced by Jamshidpey et al. in "Sets of medians in the non-geodesic pseudometric space of unsigned genomes with breakpoints", 2014. In this p…
Median inverse problem and approximating the number of -median inverses of a permutation
Poly H. da Silva, Arash Jamshidpey, David Sankoff
We introduce the "Median Inverse Problem" for metric spaces. In particular, having a permutation in the symmetric group (endowed with the breakpoint distance), we study t…
