Nilai tersebut adalah nilai p value dari uji hausman test, dimana
dalam tutorial ini nilainya sebesar 0,0000. Nilai P Value 0,000 kurang
dari 0,05 maka terima H1 yang berarti metode terbaik yang harus
digunakan adalah fixed effect dari pada random effect
UJI ASUMSI KLASIK:
1. UJI MULTIKOLINEARITAS

X4 0.867152 0.034829 -0.494332 1.000000
Dari hasil pengujian tersebut terlihat bahwa tidak adanya multikolinearitas dalam model
regresi. Karena koefisien korelasi antara variabel independen < 0,80.

Kemudian, yang perlu diperhatikan dari hasil tersebut di atas adalah nilai probablitas pada
masing-masing variabel independen. Apabila nilai prob. < 0,05 maka adanya
heteroskedastisitas. Sebaliknya apabila nilai probabilitas pada setiap variabel
independen> 0,05 maka terbebas dari planggaran asumsi heteroskedastis.
