【 摘 要 】

In repeated measurement experiment, normal linear mixed-effects model is widely used to analysis data. However, in case of detecting heteroscedasticity and the non-normality of the population distribution at the same time, normal linear mixed-effects model can give improper result of analysis. To achieve more robust estimation, we used heavy-tailed linear mixed-effects model which gives more exact and reliable analysis conclusion than standard normal linear mixed-effects model. Furthermore, we will provide the results of reliability analysis as the further work.
