Khonyakov A.A. *Osobennosti razrabotki programmnogo obespecheniya dlya postroeniya kusochno-linejnyh regressij* [Features of software development for constructing piecewise linear regressions]. *Molodaya nauka Sibiri: ehlektronnyj nauchnyj zhurnal* [Young science of Siberia: electronic scientific journal], 2021, no. 2. [Accessed 03/08/21]

*The article deals with the development of software for constructing piecewise linear regressions. The analysis of the formation of partially Boolean linear programming problems for various types of piecewise linear regressions is carried out, common points are highlighted. Based on the analysis results, a variant of the program implementation is presented in the form of a central abstract class containing common logic for all models and child classes of the models themselves.*

*As a demonstration of the operation of the software, the modeling of the ratio of the average per capita money income of the population to the value of the subsistence minimum was carried out*
