public interface FisherParams

This interface provides access to the standard parameters for Fisherian spherical statistics: mean direction, alpha-95, and k.

Note that usage of these parameters does not necessarily imply that the statistics were obtained by the original Fisher (1953) method: the McFadden & McElhinny (1988) technique produces the same parameters by a very different method.


Method Summary
 double getA95()
          Returns the alpha-95 value denoting the 95% confidence interval.
 double getK()
          Returns the k-value, an estimate of the precision parameter κ.
 Vec3 getMeanDirection()
          Returns the mean direction.
