Statistical techniques applied to aerial radiometric surveys (STAARS): principal components analysis user's manual. [NURE program]

Abstract

A Principal Components Analysis (PCA) program has been written to aid in the interpretation of multivariate aerial radiometric data collected by the U.S. Department of Energy (DOE) under the National Uranium Resource Evaluation (NURE) •program. The variations exhibited by these da,ta have. been reduced and classified into a number of linear combinations by using the PCA program. The PCA program then generates histograms and outlier maps of the individual variates. Black and white plots can be made •on a Calcomp plotter by the application of follow-up programs. All programs referred to in this guide were written for a DEC-10. From this analysis a geologist may begin to interpret the data structure. Insight into geological processes underlying the data may be obtained.
