Multi-Level Modeling for Investigators
Thursday Apr. 4, 2024 from 12:00-1:00pm
Virtual Teams Presentation
Multilevel Modeling is a statistical model that allows specifying and estimating relationships between variables that have been observed at different levels of a hierarchical data structure, including in longitudinal studies where an individual’s responses over time are correlated with each other. Multilevel models recognize the existence of the hierarchical structure by allowing for residual components at each level in the hierarchy. using multilevel models, investigators could reveal substantive values in group effect, estimate group effects simultaneously with the effects of group-level predictors, and make optimal Inference to a population of groups, from which the groups are treated as a random sample. This talk will present an overview of multilevel or hierarchical data modelling and its applications in medicine, show how to work with data for multilevel data analysis, run the necessary statistical procedures and test, and how to interpret the results from multilevel data analysis.
