The CRE model nests the conventiona

The CRE model nests the conventional fixed effects specification by introducing additional parameter heterogeneity. The advantage of CRE is that it is a flexible extension to random effect models which allows us to include both within and between variations in the model (Schunck, 2013). This approach increases model flexibility and solves the correlation between covariates and residual problem (Bell and Jones, 2015).

CRE model realizes the traditional fixed effect by introducing the heteromorphism of additional parameters. The advantage of CRE is that it is a flexible random effect model that allows us to include The variables of the model, that is, the flexibility of schschach 2013 ache.this approximation model and the relationship between solving variables.
