With the help of the previously developed application Plex, automation of planning and conducting multifactor experiments in the study of the characteristics of field-effect transistors was performed. The regression and dispersion analysis of experimental data is carried out, the quality of regression models is estimated, the influence of the number of initial experimental points on the quality of regression models is investigated. The application increases the efficiency of research related to field experiments in determining the characteristics of field-effect transistors, as it makes it possible to reduce the number of required experiments, to automate the processes of storage, extraction and processing of information.
