So it generates the panel variable as 2727 years and it won't separately stop generating quarters every time it's a new state. To decide between fixed or random effects you can run a Hausman test where the null hypothesis is that the preferred model is random effects vs. the alternative the fixed effects. As per my regression analysis the R-square value of the model was R-squared 0.369134 . Introductory econometrics: a modern approach (7th ed). It ignores time and individual characteristics and focuses only on dependencies between the individuums. and over time has given rise to a number of estimation approaches exploiting this double dimensionality to cope with some of the typical problems associated with economic data. 8!|i#}8@!$ If the error terms are correlated, then FE is no suitable since inferences may not be correct and you need to model that relationship (probably using random-effects).
