Bu çalışmanın amacı, Türkiye’de 2007 ile 2017 yılları arasındaki günlük verileri kullanılarak Borsa İstanbul
indeksi (BİST100) ve Altın Ons fiyatlarını R/S, V/S ve Periodogramanalizi kullanılarakHurst üstelini hesap- lamaktır.Zaman serilerindeki uzun dönemli bellek yapısını belirlemek için dönüştürülmüş genişlik (R/S), dö- nüştürülmüş varyans (V/S) ve yarı parametrik nitelikteki periodogram analizi geliştirilerek Hurst üsteli tah- min edilmiştir. Çalışmada BİST100 indeksi günlük getiri değerleri ve Altın ons fiyatlarını tahmin etmek için,
R istatistik paket programı kullanılmıştır. Hurst üsteli tahmin sonuçları, BİST100 indeksi ve Altın Ons fiyatları
serilerinin uzun dönemli bellek yapısı taşıdığı gözlemlenmiştir

The aim of this study is to calculate the Hurstexponent by using R / S, V / S and Periodogram analysis for Bor- sa Istanbul index(BIST100) and Gold Ounceprices in Turkey for the daily period of 2007-2017. Hurstexponent
is estimated by developing transformedwidth (R/S), transformed variance (V/S) and semi-parametric perio- dogram analysis in order to determine the structure of long-termmemory in time series. In this study, forthe
estimation of daily BIST100 index returnvalues and gold ounce prices, the R statistical software program are
used. Hurstexponent estimation results hows that the daily series of BIST100 index and Gold Ons prices have
long-term memory structure
