RESEARCH OF THE CHANGE TREND OF EVALUATION ERRORS OF THE COVERAGE FACTOR IN INDIRECT MEASUREMENTS
Przemyslaw Otomanski
Abstract:
The results of research of evaluation error of the coverage factor with approximate method of effective number degrees of freedom in indirect measurements have been presented in the paper. Comparison of the results obtained with the known evaluation of these errors in direct measurements enabled to determine the change tendency of the errors of coverage factor evaluation, when the number of components of standard uncertainties grows. The knowledge of coverage factor characteristics for the convolution of three selected probability distributions was used for the research.
