So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

Abstract:

Çalışmada Dolar, Euro ve Sterlin döviz kuru serilerine ilişkin getiri oynaklığı modellemesi yapmak amaçlanmıştır. Bu amaç doğrultusunda 05.01.2000-13.09.2018 dönemindeki günlük verilerin sürekli getirileri hesaplanarak analiz kapsamında incelenmiştir.  Oynaklık modellemesi için serinin durağanlığı sağlanmış, Schwarz bilgi kriteri esas alınarak en uygun ARMA başlangıç modeli belirlenmiş ve serilerdeki değişen varyans, otokorelasyon ve doğrusal olmayan unsurların varlığı araştırılmıştır. Analiz sonucunda, EUR serisi için GARCH (2,1), USD serisi için EGARCH (1, 2) ve GBP serisi için IGARCH (1,1) modelleri ile oynaklık modellemesi gerçekleştirilmiştir. Model sonuçlarına göre, EUR serisi için oynaklığa etki eden şokların kalıcı bir etki yaratmadığı tespit edilirken, EUR serisine gelen bir şokun etkisinin ve şoku üzerinden atmasının yaklaşık 8.09 gün sürdüğü belirlenmiştir. USD serisinde meydana gelen pozitif bir şokun, aynı büyüklükteki negatif şoktan daha fazla etki yarattığı ve şokların getiri oynaklığı üzerinde asimetrik bir etkiye sahip olmadığı ortaya çıkarılmıştır. Ayrıca USD serisine gelen bir şokun etkisinin yaklaşık 2.30 gün sürdüğü de belirlenmiştir. GBP serisinde ise şokların kalıcı bir etki yarattığı ve ağırlıklı olarak bir önceki dönemde meydana geldiği tespit edilmiştir.

Abstract:

The aim of this study is to model the volatility of the Dollar, Euro and Sterling series. In this direction, permanent return of daily data in 05.01.2000-13.09.2018 period is calculated and analyzed within the scope of analysis. The stationary of the series is provided for volatility modeling, and the optimal ARMA starting model is determined on the basis of the Schwarz information criterion and the variance, autocorrelation and nonlinear elements are investigated in the series. As a result of the analysis, the volatility models of the series are analyzed by GARCH (2.1) model for EUR series, EGARCH (1.2) for USD series and IGARCH (1.1) models for GBP series. According to the results of the model, it is found that the impacts on the volatility of the EUR series don't have a lasting impact and the effect of shock lasted 8.09 days. A positive shock from the USD series are more influenced by negative shock of the same magnitude and the shock is not asymmetric on return volatility. Furthermore, it is determined that effect of shock lasted 2.30 days. In the GBP series, the shocks have a lasting effect and predominantly occurred in the previous period.
