| Abstract: | When more then one measured signal is used in activation analysis or more then one sample of a material is analysed in the same batch, there is a problem of correlation. Algorithms are derived and tested for the calculation of calibration coefficients and their covariance matrix and for the calculation of the final result from the analysis of several subsamples. The results compare favourably with the results of other computational procedures in use. |
