However, the general requirements of schools are not high and the quality is average. As long as you are serious and willing to spend time, it is generally no problem. A better university requires more, which may take a long time to complete, but most people can pass, and very few people will fail because of various wonderful problems.

At present, 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.
