Abstract
An algorithm, based on convex quadratic programming, is proposed to sm ooth sample histograms. The resulting smoothed histogram remains close to the original histogram and honors target mean and variance. The al gorithm is extended to smooth sample scattergrams. The resulting smoot hed scattergram remains close to the original scattergram shape and th e two previously smoothed marginal distributions and honors the target correlation coefficient.
