1. A method for processing seismic data, comprising: performing a plurality of stochastic simulations for one or more rock model parameters to generate one or more anisotropic parameters for a subsurface area of the earth; deriving one or more joint multi-dimensional probability density functions for the anisotropic parameters generated by the stochastic simulations; computing one or more posterior probability density functions from measured well log data and the joint multi-dimensional probability density functions; deriving one or more anisotropic profiles from the posterior probability density functions; generating a seismic image from the anisotropic profiles; and displaying the seismic image.
