چکیده

A variable span scatterplot smoother based on local linear fits is described. Local cross-validation is used to estimate the optimal span as a function of abscissa value. A rejection rule is suggested to make the smoother resistant against outliers. Computationally efficient algorithms making use of updating formulas and corresponding FORTRAN subroutines are presented.

In April 1957, Stanfc:rd University proposed the construction of a two-mile long linear electron accelerator capable of accelerating electrons to energies of 10 to 20 CeV for use in physics research. Congressional authorization for this machine was given in September 1961, and construction of the Stanford Linear Accelerator Center (SLAC) started in July 1962 on 480 acres of land near Stanford U...
