This article introduces a method for computing weighted averages on spheres based on least squares minimization that respects spherical distance. We prove existence and uniqueness properties of the weighted averages, and give fast iterative algorithms with linear and quadratic convergence rates. Our methods are appropriate to problems involving averages of(More)
Alteration in dopamine D1 receptor-mediated signal transduction following repeated cocaine administration was investigated. Male Fischer rats were administered saline or cocaine HC1 (15 mg/kg, i.p.) three times daily at 1-h intervals for 1, 7, or 14 days.
