Summary
Analisis Induktif Berdasarkan pengolahan data dengan bantuan program Eviews 6, diperoleh hasil olahan data untuk berbagai uji dan model analisis sebagai berikut: Uji Stasioner Uji stasioner yang digunakan dalam penelitian ini adalah uji akar unit (unit root test) yang dikembangkan oleh David Dickey dan Wayne Fuller, atau yang lebih dikenal dengan uji akar unit Dickey-Fuller (DF). Apabila nilai statistik Dickey-Fuller (Dickey-Fuller test statistic) probabilitasnya kecil dari α = 0,05, maka H0 ditolak atau Ha diterima yang artinya variabel tersebut stasioner. Variabel tersebut dapat stasioner apakah itu pada level, 1st difference, atau 2nd difference. Sebaliknya apabila nilai statistik Dickey-Fuller probabilitasnya besar dari α = 0,05, maka H0 diterima atau Ha ditolak yang artinya variabel tersebut tidak stasioner atau mengandung masalah unit root. Tabel 1 menjelaskan masingmasing variabel stasioner pada tingkat tertentu, yaitu pada level, 1st difference, dan 2nd difference. Dari Tabel tersebut dapat diketahui bahwasannya variabel-variabel tabungan, investasi, pengeluaran pemerintah, konsumsi periode sebelumnya serta suku bunga memiliki nilai probabilitas yang kecil dari α = 0,05 pada 1st difference, oleh karena itu variabel-variabel tersebut stasioner pada 1st difference.
