 abstract={Assuming correlation only within the results of measurement repetitions for each quantity observed in a network, equivalence has been proved for two forms of parametric adjustment model, which differ in the approach to measurement repetitions and are called the one-stage and the two-stage model respectively. As a complement to the known criterion of imperceptibility of disturbances in observations, the criterion of imperceptibility of correlation between the components of the observation vector has been formulated, which applies to each of the modules of the two-stage model. Assuming the structure of the observation error, being slightly developed as compared to the standard structure, the cases of meeting of each of the above criteria in those modules have been presented. Then, the relationship which combines measures of internal reliability for both the adjustment models under question has been given.},
