基于主客体互依中介模型分析成对数据中的中介效应
Chinese Journal of Health Statistics(2021)
Abstract
目的 介绍主客体互依中介模型(actor-partner interdependence model extended to mediation,APIMeM)及其实现过程,为相关领域的学者提供方法学的参考.方法 介绍APIMeM的基本思想和模型构建步骤,并在MPLUS软件中构建APIMeM的结构方程模型分析具体实例.结果 根据成对数据是否可区分构建对应的饱和模型,采用极大似然估计效应值,包括主体效应、伴侣效应、中介效应等.采用偏差校正bootstrap法估计效应值的置信区间.结论 APIMeM可应用于成对数据中的中介效应分析,结构方程模型是实现该模型的常用方法.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
