Apabila estimasinya RE, maka tidak perlu pakai cross section weight, jadi langsung bisa pilih koefisien white period (heteroskedastis dan autokorelasi), white diagonal (heteroskedastis), white cross section (heteroskedastis dan cross sectional dependent) atau menggunakan SUR, Parks dan PCSE (heteroskedastis, autokorelasi dan cross sectional dependent). A few additional things are also important to note. Often, you will only be interested in the correlations of a few of your variables.
