Program PREGA Pivotal Regression Analysis of Gamma-Ray Spectra from NaI(T1) Detectors for the ND6620 Computer.

Abstract

Program PREGA was developed at NRL to perform a fast and efficient regression analysis of a gamma ray spectrum from an unknown source, taken with a NaI(T1) detector. The analysis determines the best subset from a library of standard spectra to use in fitting the data. Output at each step includes relative intensities and uncertainties for each standard used in the fit, plus the partial F statistic for significance of each library element. Final output includes an analysis of variance (ANOVA) table, distribution of residuals, location of largest residuals, distribution of runs of consecutive residuals with the same sign, and the location of largest runs. The program was written for the Nuclear Data ND6620 computer and has been transferred to VAX II/780.
