Philosophical papers usually don't need regression analysis. Regression analysis is a statistical method to process and analyze numerical data, which is mainly used to study the relationship between variables and forecasts. Philosophical papers pay more attention to speculative, theoretical and conceptual discussions, and pay attention to the essence, significance and philosophical thinking of problems.

In the field of philosophy, the thesis may involve criticizing philosophical theories, discussing philosophical issues, discussing ethics, metaphysics, epistemology and other fields. Argumentation and analysis play an important role in philosophical papers, but they are usually carried out through logical reasoning, ideological exposition and criticism, and there is no need to use statistical means such as regression analysis.

Of course, in specific research situations, if it is necessary to combine statistical data for analysis, such as some empirical philosophical research, then regression analysis and other methods may be used. But this situation is relatively rare.

In short, the research methods and writing methods of philosophical papers are diverse, and whether regression analysis is needed depends on your research topic and method requirements.
