“…Time-series data can be represented using different kinds of signal transforms such as Fourier and wavelet transforms. Wavelet transform has been found to outperform Fourier transform in analyzing non-stationary data; thus making it a good candidate for time-series decomposition [38]. Wavelet methodology was first introduced by Grossmann and Morlet [39].…”

“…Eğitim ve test sonuçları bir arada incelendiğinde histogram eğrilerinden eğitim aşamasında ortalama hatanın 0 dolara yakın olduğu ve standart sapma değerinin 16 dolar civarı olduğu test aşamasında ise ortalama hatanın 12,5 dolara yakın olduğu fakat standart sapma hatasının 60 dolar mertebesine yükseldiği görülebilmektedir. Kılıç ve Arkadaşlarının gerçekleştirdiği çalışmada [24] ise 1 Ocak 1990 ile 1 Ocak 2011 arasındaki S&P borsa verisinden dalgacık katsayıları çıkartılarak ARIMA regresyon yöntemi kullanılmıştır. Önerilen çalışma ile Kılıç ve arkadaşlarının elde ettikleri RMSE sonuçları karşılaştırıldığında eğitim hatasının önerilen çalışmaya göre yaklaşık 5 dolarlık bir hata yaptığı gözlemlenmektedir.…”

“…The assessment of the dependence between economic and financial changes has been the contribution of several operations research scholars in recent years (Bernard et al, 2018 ; Khalilpourazari & Hashemi Doulabi, 2021 ; Kılıç & Uğur, 2018 ; Tzagkarakis & Maurer, 2020 ). Operations research scholars have examined economic and financial systems as complex harmonized models.…”
