Graphics Research based on LOWESS

摘要

Statistical graphics are intuition and easy to understand. Statistical graphics can be flexibly drawn according to the research targets. This makes it very meaningful to theoretical research and its application in our daily life. Graphics is used to do exploratory analysis in this article. The most frequently used statistical graphic to describe the dependence between the variables is scatter diagram. To observe the dependence between the variables and at the same time predict the model of the relation between both variables we drew the scatter diagrams based on LOWESS and did the stability test by using the Bootstrap method. We drew the scatter diagram and the smooth scatter diagram with simulated data and did the data analysis with real data. We drew the scatter diagram and the predicted curve diagram with LOWESS and found that the data model and the diagram fit well. At the same time, we have supplied the R program code and the advices for the users.
