As follows:

Now writing a paper needs an empirical process, that is, using a model to fit the data and achieve the expected results. The empirical models in this paper mainly include: ordinary regression, static panel regression, dynamic panel regression, threshold regression, breakpoint regression, two-stage regression, double differential regression, quantile regression, logical regression, spatial regression, structural equation and time series.

The models for determining the comprehensive score of weight calculation mainly include factor analysis, principal component analysis, entropy method, analytic hierarchy process and fuzzy comprehensive evaluation method. The model applied by undergraduates can be a little simpler, and ordinary regression is similar to static panel regression. The model of graduation thesis is complex, and the threshold model and breakpoint model are widely used at present.

The chapter of empirical analysis directly determines the value of the whole article and whether it can go on smoothly. Therefore, for the thesis at this stage, the chapter of empirical analysis is the core of an article, and it is also the first chapter that every student who writes a graduation thesis has to deal with. As long as the content of this chapter is decided, the whole article will follow suit.

Why is the empirical part the most important and should be written first? First, it is meaningless for the empirical part not to pass the whole article, so there is no need to write it down, and it may be necessary to change the theme; Second, once the argument is passed, the problem you are most worried about will be solved. You have also read some documents and gained a deeper understanding of the research topic. You have a good idea about the whole article.

So students, if you have empirical requirements, please write the empirical part first. Even if you don't write, you must first make the results of data processing.

How to do empirical analysis? First of all, we should make clear our research topic, because the research topic generally determines the dependent variables and core independent variables of the empirical model, such as "pension income and labor supply of rural elderly population-analysis based on breakpoint regression". From the topic, it can be determined that the dependent variables of the article are the labor supply of the rural elderly population and the independent variable pension income, and the model used is breakpoint regression.
