Types of panel data:-

1) Pooled model
2)Fixed model
3)Random model

Data set :- "Produc"
Index :- "state", "year"

                                                                          Fig:1

                                                                           Fig:2

                                                                         Fig :3

                                                                          Fig:4

                                                     
   

                                                                          Fig:5

Explanation:-The p-value is insignificant so the dummy variable has significant effect therefore we can not use pooled panel data instead we use fixed data.

                                                                        Fig:6

Explanation :-The p-value is insignificant so dummy variable has significant effect therefore we can not use  pooled instead we use random data.So pooled data is neither good than fixed data nor random data.

                                                                     Fig:7            

  Explanation:- Here as the p value is very low so the alternative hypothesis is valid and therefore  fixed data is better than random data.
