In article the approach to the estimation of program reverse semantic traceability (RST) influence on program reliability with assistance of object-oriented metrics is proposed. In order to estimate reasonability of RST usage it is naturally to define how it influences on major adjectives of software development project: project cost, quality of the developed application, etc. At present object-oriented metrics of Chidamber and Kemerer are widely used for predictive estimation of software reliability at early stage of life cycle. In number of works, for example, [6-7], it is proposed to use logistic regression for estimation of probability π (that a module will have a fault). The parameters of this model are found by maximal likelihood method with calculation of object-oriented metrics. The paper shows how to change the software reliability model parameters, that was received using logistic regression, in order to estimate influence of program RST on program reliability.
