Statisticians have long used moving average type smoothing and classical regression analysis techniques to reduce the variability in data sets and enhance the visual information presented by scatterplots. This thesis examines the effectiveness of Robuts Locally Weighted Regression Scatterplot Smoothing (LOWESS), a procedure that differs from other techniques because it smooths all of the points and works unequally as well as equally spaced data. The LOWESS procedure is evaluated by comparing it to previously validated uniform and cosine weighted moving average and least squares regression programs. Interactive APL and FORTRAN programs and detailed user instructions are included for use by interested readers 2012-11-19T23:50:35Z 2012-11-19T23:50:35Z 1984-09 Thesis http://hdl.handle.net/10945/19419 en_US This publication is a work of the U.S. Government as defined in Title 17, United States Code, Section 101.
