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.

Nilai dw sebesar 1.79155, bandingkan dengan nilai tabel tingkat signifikan 0,05, jumlah sampel 48 (n) dan jumlah variabel independen 4 (k=4), lihat nilai pada tabel 4. sbb:

Tabel durbin watson tingkat signifikan 0,05

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.
