Consider a Bayesian optimal design with many support points which poses the problem of collecting data with a few number of observations at each design point. Under such a scenario the asymptotic property of using Fisher information matrix for approximating the covariance matrix of posterior ML estimators might be doubtful. We suggest to use Bhattcharyya matrix in deriving the information matri...

We present a strategy for selecting the values of model parameters by comparing walkaway Vertical Seismic Profiling data with multilayered in context Bayesian Information Criterion. consider -wave traveltimes and assume elliptical polar velocity dependence. A different propagation speeds, depending on angle propagation, can be good approximation medium composed thin layers. While anisotropy one...
