WebGenerally, the fixed effect model is defined as y i t = β X i t + γ U i + e i t where y i t is the outcome of individual i at time t, X i t is the vector of variables for individual i at time t. U i is a set of unobservables for individual i. Notice that those unobservables are unchanging through time, hence the lack of the time subscript.
