Estimation of nonstationary PEFs

As shown by Margrave (1998), the generalization of stationary convolution to the non-stationary case can be done in two different ways called non-stationary convolution and non-stationary combination. As identified by Rickett (2001), our programs at the Stanford Exploration Project implement non-stationary combination. This section intends to explain in a matrix form the filter estimation step for non-stationary PEFs for both non-stationary convolution and combination.
