Available in PDF, EPUB and Kindle. Book excerpt: A large computer code was written to perform a number of discriminant analysis procedures on aerial radiometric data. Work on percentile estimation, using the normal and log-normal probability distributions, was extended. Additional work was performed on methods of computing with large data sets. Attempts are being made to evaluate the behavior of principal components analysis relative to element distribution in a survey area. We also provided general statistical consulting in such areas as discriminant analysis, filtering, and kriging.

Available in PDF, EPUB and Kindle. Book excerpt: During the period covered by this report, the authors investigated the serial properties of aerial radiometric data. Results were applied to the choice of minimum segment width in the maximum variance segments algorithm and to the use of aerial radiometric data in the design of ground sampling experiments. The report also presents the results of a comparison of normal and lognormal percentile estimation techniques. Twenty-two quadrangles are being analyzed in the search for a uranium favorability index. Computer codes developed during this investigation have been provided to the Bendix Field Engineering Corporation in Grand Junction, Colorado.

Available in PDF, EPUB and Kindle. Book excerpt: During the period covered by this report, we proposed a method of comparing aerial and ground data as a means of assessing the quality of aerial data. We also compared two methods of partitioning count rates among several isotopes. Time-series analysis and analysis of variance were considered as tools for using aerial radiometric data to aid in designing ground-based sampling experiments. Several methods of computing covariance matrices were compared for use with very large data sets. A study showed a potential for using aerial radiometric data to rank quadrangles according to the Department of Energy's estimated uranium inventories. A discriminant analysis code was transferred to Grand Junction, and several statistics short courses were presented there. Recommended cluster analysis procedures were developed and applied to aerial radiometric data. Reports and papers were prepared on topics such as outlier detection, percentile estimation, discriminant analysis, and statistical package comparison.

Available in PDF, EPUB and Kindle. Book excerpt: During the period covered by this report, we analyzed the radiometric data collected along the Texas Gulf Coast using ten discriminant analysis techniques to establish radiometric signatures and classify new observations. We conducted a survey of several methods for computing the covariance matrix of large data sets, with particular interest to one-pass algorithms. An investigation of methods of estimating upper-tail percentiles for aerial radiometric data was begun. A feasibility study was conducted concerning the design of ground-based sampling plans using a statistical model for the correlation between observations taken along a flight line. A study of the use of cluster analysis in aerial radiometric data analysis was initiated. Two short courses on statistical methods were presented in Grand Junction, Colorado, and more are planned.
