Statistical models usually of structural equation models that explain the interrelationship between key variables to understand the impact of each variable and predict one or more issues of interest with minimal error. Multi-sample models, multilevel models, multitrait-multimethod models and longitudinal models or models with latent growth curve trajectories. These models test invariance in its different phases of expression, they also allow us to approach AFC, path models, covariance structure models, hybrid EFA models, MIMIC models... in other words, they provide us with a great versatility to capture, to model the complex reality of trying to explain the quality of life in citizenship. In this line, researchers of the group based in the area of Methodology of Knowledge Sciences participate the most.
