10. Model Estimation Where Represents dependent variable for regions i , and time t . Is observed variables (independent variables) unobserved error term Is the subject specific residual and represents unmeasured individual factors which affects y (unknown intercept for each entity. NB: “If unobserved variable does not change over time, then any changes in the dependent variable must be due to influences other than these fixed characteristics” (Stock and Watson, 2003, p.289-290). Is the coefficient for the independent variables (slopes) Intercept (Model constant)

Motivation for Fixed effects are OLS models consistently population average while correlation may exist within the period Fixed effects allows analysis of unbalanced data and missing periods, not dropped as OLS does Allows nesting between regions, months and years The objective is to generalise and trend the coefficient using SD Provides a better analytical and robust result for highly correlated data
