Poisson activation analysis

Note 6. Combining the inequality constraint 0] with known Internal Poisson variance has been used by Guinn for total variance estimation in activation analysis ( 2), by Donahue (88) for the same purpose in accelerator mass spectrometry, by Heydorn (18.89) for the analysis of precision of gamma ray spectrum analysis, and by Currie ( ) for optimal weighting in counting experiments. The variance weighted t approximation derives from work by Cochran (90). Cochran s work, however, applied to a somewhat different model than used here. The statistical properties of this extension of his technique have not been studied.
