It is very difficult to analyze and mine massive and high-dimensional data. Although the current hardware conditions have greatly improved, they still cannot meet the needs of large-scale, high-dimensional data. In medical research, scientific experiments, and biological gene sequencing, a combination of analysis of variance and principal component analysis was used to study the above issues. On this basis, this article started from two main data analysis methods and studied the relevant theories and algorithms of binary analysis of variance and principal component analysis, in order to achieve the analysis of sample data. The experiment proved that the data analysis based on the system in this article can combine the factor load matrix of the main factor variables to evaluate the contribution of each factor in the investment portfolio to the overall risk. Finally, the optimal stock portfolio was 601989, 601601, 600028, 600104, 601857, and 601988.

The study of the educational process of university students has revealed their need for more engagement in class. They seem unable to absorb material that does not require a certain level of mental tension, negatively affecting their academic performance and competence. Therefore, there is a need to develop pedagogical technology to optimize the educational process. We analyzed the educational process at the National University “Odesa Law Academy” in 2020-2023. We evaluated the effectiveness of ways and means of enhancing the academic and cognitive skills of 150 full-time IT students during their study of professional-oriented courses. We have improved students' educational and mental activities by optimizing the educational process through personalized problem-based learning, utilizing professionally oriented problem situations, and providing favorable motivational and emotional support. We confirmed the reliability of the research results using descriptive statistics.

The principle of multiplicity is introduced for the components of the investment planning process. Some algorithms are given that ensure the process of investment planning at the regional level: the formation of integrated assessments of investment projects, automated generation of projects, multicriteria evaluation and selection of projects, taking into account the mutual influence of projects, optimizing the composition of projects, and taking into account financing restrictions. The features of the program system intended for the formation of plans for the territorial and sectoral development of the region are considered.
