Abstract:
|
We consider using stochastic gradient descent (SGD) procedure to fit spatial auto-regressive quantile models to lattice data, incorporating a recently developed perturbation method to obtain standard errors in addition to model parameter estimates. We derive the SGD update equations and perform a simulation study to examine the empirical coverage of confidence intervals constructed using the perturbation procedure.
