koefisien yang dihasilkan dengan uji park yaitu:
Log(res2) = -1,75 - 0,22 GDPgr – 0,0006 d(kurs) + 1,817 d(Birate,2) t-statistik -3,34 -0,94 -0,77 0,81
p-value 0,0019 0,35 0,45 0,43
Dari output di atas dapat dilihat bahwa koefisien masing-masing variabel independen bersifat tidak signifikan, maka dengan demikian dapat disimpulkan bahwa tidak ada masalah heteroskedastisitas pada model.

H0 : tidak ada autokorelasi jika, du < dw < 4-du
Perbandingan nilai durbin watson dengan nilai tabel diperoleh nilai dw 1.792 lebih besar dari batas atas (du) 1,720 dan kurang dari 4 - 1,720 (4 – du), maka dapat disimpulkan bahwa H0 diterima yang menyatakan tidak ada autokolerasi positif maupun negatif/ tidak terdapat autokorelasi.
