In econometrics, random effects models are used in the analysis of hierarchical or panel data when one assumes no fixed effects (it allows for individual effects). The random effects model is a special case of the fixed effects model.here are two common assumptions made about the individual specific effect, the random effects assumption and the fixed effects assumption. The random effects assumption (made in a random effects model) is that the individual specific effects are uncorrelated with the independent variables.
(See Random Effects .) Such models are also called variance component models. Random effect models are often hierarchical models. A model that contains both fixed and random effects is called a mixed model. Repeated measures and split-plot models are special cases of mixed models.Often the term mixed model is used to subsume random effect models.o specify a random effect, highlight it in the Construct Model Effects list and select. This appends &Random to the effect name in the model effect list. (For a definition of random effects, see Random Effects .) Random effects can also be specified in a separate effects tab.
