Tento postup popisuje model kalibrácie ako mnohorozmerný model s chybami v premenných, ktorý je linearizovaný a výsledné riešenie sa získava pomocou iterácií. A new statistical procedure for evaluating the calibration of thermocouples is presented. This procedure describes the calibration model as a multivariate errors-in-variables model which is linearized and the resulting solution is found by iterations Public work category AFC No. of Archival Copy 43935 Catal.org.

V príspevku sa dáva dôraz na výhody prístupu vzorkovania z distribúcie výstupných veličín cez charakteristické funkcie založenom na distribúcii typu kopula vstupných veličín s marginálnymi distribúciami daného konvolučného typu. Proper uncertainty analysis in metrology frequently requires using model with a nonlinear measurement equations and non-trivial joint multivariate distribution of the input quantities. In the paper we emphasize the advantage of using the Characteristic Function Approach for sampling from the distribution of the output quantities, based on the joint copula-type distribution of the input quantities with given convolution-type marginal distributions.

The verification is done by using certified reference materials of ethanol in nitrogen in 4 concentration levels of ethanol. Here we offer an overview of steps, which are checking the traceability of measurement from the process of verification up to traceability of used reference material to SI unit of mass kg.

In a metrological context, this problem is closely related to evaluation of the interlaboratory comparison experiments, and in particular, to determination of the reference value (estimate) of a measurand and its uncertainty, or alternatively, to determination of the coverage interval for a measurand at a given level of confidence, based on such comparison data. We present a brief overview of some specific statistical models, methods, and algorithms useful for determination of the common mean and its uncertainty, or alternatively, the proper interval estimator. We illustrate their applicability by a simple simulation study and also by example of interlaboratory comparisons for temperature. In particular, we shall consider methods based on (i) the heteroscedastic common mean fixed effect model, assuming negligible laboratory biases, (ii) the het Public work category ADC No. of Archival Copy 34273 Catal.org.
