Assuming that the x-coordinates of impact points of rounds fired at a target centered at the origin, xo, are the sums of correlated aim errors and independent ballistic errors, the author shows how the likelihood function of the unknown statistical parameters, associated with a sample x1, x2,..., XN of impact points from a single burst, can be quickly and simply computed. The likelihood function is used here as the basis for estimating the parameters, and the results of the estimates, applied to a large number of computer simulations, are summarized.
