                            <p>Gompertz flexible Weibull  dağılımı, flexible Weibull dağılımının bir türüdür. Biz Gompertz flexible Weibull dağılımının parametrelerinin tahmini problemini ele aldık.  Gompertz flexible Weibull dağılımı için birkaç tahmin yöntemi üzerinde durduk. En çok olabilirlik, en küçük kareler, ağırlıklandırılmış en küçük kareler, Anderson Darling ve Cramer-von Mises tahmin edicileri düşünülmüştür. Bu tahmin edicileri yan ve hata kareler ortalaması açısından karşılaştırabilmek için bir Monte Carlo simülasyon çalışması yapılmıştır. Ayrıca Gompertz flexible Weibull dağılımının kullanışlılığını göstermek ve bahsedilen beş tahmin yöntemine dayalı olarak tahminleri elde etmek için gerçek veri çalışmaları sunulmuştur.</p></trans-abstract>

We tackle the problem of estimation of parameters of Gompertz Weibull distribution. We discuss several methods of estimation for Gompertz flexible Weibull distribution. Maximum likelihood estimators, least squares estimators, weighted least squares estimators, Anderson-Darling estimators, Cramer-von Mises estimators are considered. A Monte Carlo simulation study is performed in order to compare these estimators in terms of their biases and mean square errors. Also, real data applications are presented to illustrate the usefulness of Gompertz flexible Weibull distribution and obtain estimates based on five methods of estimation.</p></abstract>
