If the R-squared (the proportion of variance in the response variable that can be explained by the explanatory variables) in the second model is significantly higher than the R-squared in the previous model, this means the second model is better.

I estimate the project to require about 3-4 hours of work. 1 What is a hierarchical regression analysis? Hierarchical Linear Modeling: A Step by Step Guide Utilize R for your mixed model analysis In most cases, data tends to be clustered. A hierarchical linear regression is a special form of a multiple linear regression analysis in which more variables are added to the model in separate steps called "blocks." This is often done to statistically "control" for certain variables, to see whether adding variables significantly improves a model's ability to . 2020 Jul 1;2020(56):176-187. doi: 10.1093/jncimonographs/lgaa004.
