Likelihood ratio tests for a mixture of two von Mises distributions.

摘要: SUMMARY. It is proposed that the orientation of elongate objects, such as bones, may be used to identify flow direction ancient river deposits. If true, objects could great value when bedforms ripples and dunes are not visible. Two sandstone quarries were investigated wherein paleoflow was determined from both dinosaur bones. A mixture two von Mises distributions captures observation bones transported under unidirectional conditions will align parallel perpendicular direction. Likelihood ratio tests for a given. The power these by simulation since agrees with primary if hypothesis test comparing dominant mean fails reject. likelihood on has reasonable power. directions in distribution ir apart, more powerful can used. exactly apart useful determining assumptions satisfied.
