Abstract
A method is presented for estimating the confidence region for the mean of a set of axes that are noncircularly distributed about the mean axis. The data (plotted on the upper hemisphere) are projected, through lambert's equal-area projection, onto the plane that is tangent to the estimated mean. An elliptical confidence region is constructed around the projected mean using bivariate normal theory. The confidence region is then projected back to the sphere. The method is applied to the analysis of a set of joint orientations.
