基于DNA甲基化推断年龄的建模方法与影响因素
Modeling Methods and Influencing Factors for Age Estimation Based on DNA Methylation
摘要
Abstract
Age estimation based on tissues or body fluids is an important task in forensic science.The changes of DNA methylation status with age have certain rules,which can be used to estimate the age of the individuals.Therefore,it is of great significance to discover specific DNA methylation sites and develop new age estimation models.At present,statistical models for age estimation have been de-veloped based on the rule that DNA methylation status changes with age.The commonly used models include multiple linear regression model,multiple quantile regression model,support vector machine model,artificial neural network model,random forest model,etc.In addition,there are many factors that affect the level of DNA methylation,such as the tissue specificity of methylation.This paper re-views these modeling methods and influencing factors for age estimation based on DNA methylation,with a view to provide reference for the establishment of age estimation models.关键词
