| Summary: | Objective Explore the implementation of generalized estimation equations (GEE) and mixed linear models (MLM) in longitudinal data analysis using Python software, and expand its application in statistical analysis.Methods GEE and MLM were constructed by Python software to explore the impact of PM2.5 on lung function (forced expiratory volume in1second, FEV1) with an example of environmental epidemiology, and compared with the results of R software.Results With PM2.5 increases of 1 μg/m3, the FEV1 of the subjects decreased by 8 mL after 2 days. Python software can use a statsmodels library to analyze MLM and GEE, and the program language is concise, the program logic has a certain similarity when compared with R, the calculation results of parameter estimation and confidence interval are almost the same, and the Python result is reliable.Conclusion Python software can flexibly construct MLM and GEE, which has a certain reference value in practical research. |
