1, you need to learn or review the contents of high numbers, line generation and probability theory.
Mathematical modeling usually requires knowledge of high numbers, line generation and probability theory. Without this knowledge, it is difficult to analyze problems and build models. Without a model, how can we draw a conclusion? So it is necessary to spend some time studying or reviewing advanced mathematics, line generation, probability theory and so on.
2, need to learn MATLAB, SPSS and other software.
Mathematical modeling is generally programmed with MATLAB, and data is sorted with MATLAB. Sometimes data is processed with SPSS, such as factor analysis with SPSS. If you don't know these two softwares, it is still very difficult to participate in the mathematical modeling competition.
