Adaptive treatment allocation and selection in multi-arm clinical trials: a Bayesian perspective
Elja Arjas, Dario Gasbarra
Clinical trials are an instrument for making informed decisions based on evidence from well-designed experiments. Here we consider adaptive designs mainly from the perspective of m…
On a new Sheffer class of polynomials related to normal product distribution
Ehsan Azmoodeh, Dario Gasbarra
Consider a generic random element in the second Wiener chaos with a finite number of non-zero coefficients in the spectral represent…
Estimation of Viterbi path in Bayesian hidden Markov models
Jüri Lember, Dario Gasbarra, Alexey Koloydenko +1
The article studies different methods for estimating the Viterbi path in the Bayesian framework. The Viterbi path is an estimate of the underlying state path in hidden Markov model…
Eigenvalues of random matrices with isotropic Gaussian noise and the design of Diffusion Tensor Imaging experiments
Dario Gasbarra, Sinisa Pajevic, Peter J. Basser
Tensor-valued and matrix-valued measurements of different physical properties are increasingly available in material sciences and medical imaging applications. The eigenvalues and…
Convergence rate for the hedging error of a path-dependent example
Dario Gasbarra, Anni Laitinen
We consider a Brownian functional with and a singular deterministic . We deduce the -convergence rate for the approximati…
