Analysis of the modified weibull distribution for estimation of wind speed distribution
Yenilmez, İsmail; Mert Kantar, Yeliz; Arık, İbrahim; Usta, İlhan (Association for Computing Machinery, 2015)Finding suitable wind speed distribution is one of the most important tasks for the correct estimation of wind energy potential of the specified region. The Weibull distribution is the well-known and suggested distribution ... -
Distributions of Wind Speed at Different Heights
Mert Kantar, Yeliz; Usta, İlhan; Arık, İbrahim; Yenilmez, İsmail (IEEE, 2016)In this study, the parameters of different distributions such as the Weibull, Rayleigh, Lognormal, Gamma and Generalized Gamma, which are used for modelling wind speed, at the different heights 10 and 30 m, have been ... -
Estimation of Censored Regression Model in the Case of Non-Normal Error
Yenilmez, İsmail; Mert Kantar, Yeliz; Acıtaş, Şükrü (Yildiz Technical University, 2018)For the censored regression model, it is well-known that while classical least squares estimation yields biased and nonconsistent estimator, maximum likelihood estimator (MLE) is consistent and efficient. Tobit estimator ... -
Evaluation of robust estimation methods in estimating weibull parameters for wind energy application
Arık, I.; Mert Kantar, Yeliz; Usta, İlhan; Yenilmez, İsmail (Association for Computing Machinery, 2015)Two-parameter Weibull distribution has been widely-used reference distribution in wind energy studies and thus its parameter estimation methods have been well-studied in the literature. However, the literature have generally ... -
A new estimation approach based on moments for estimating Weibull parameters in wind power applications
Usta, İlhan; Arık, İbrahim; Yenilmez, İsmail; Mert Kantar, Yeliz (Pergamon-Elsevier Science LTD, 2018)This study introduces a new estimation approach that could be used in calculating the Weibull parameters for the estimation of wind power. This new approach, called the method of multi-objective moments (MUOM), proposes ... -
A Statistical Investigation on Wind Energy Potential of Northwest of Turkey
Usta, İlhan; Mert Kantar, Yeliz; Arık, İbrahim; Yenilmez, İsmail (IEEE, 2016)The northwest of Turkey is an important region which is a rapidly developing industrial center. Thus, energy analysis of this region has a high importance for the region's geopolitical, economic and demographic structure. ... -

A Study on Estimation of Wind Speed Distribution by Using the Modified Weibull Distribution
The knowledge of the probability density function of wind speed is key information for the determination of wind energy potential of the specified region. In the literature, the Weibull distribution is a widely-used and ... -
Sınırlı bağımlı değişkenli modeller ve tahminleme yöntemleri
Yenilmez, İsmail (Anadolu Üniversitesi, 2017)Regresyon modelinde, yalnızca iki değer alabilen veya negatif değer alamayan veya belli aralıklarda değer alan bağımlı değişkenler sınırlı bağımlı değişken olarak tanımlanmaktadır. Sürekli bağımlı değişken belli aralıkta ... -
Wind speed analysis using the Extended Generalized Lindley Distribution
Mert Kantar, Yeliz; Usta, İlhan; Arık, İbrahim; Yenilmez, İsmail (Pergamon-Elsevier Science LTD, 2018)The wind energy potential of a specified region can be estimated using the distribution of wind speed. Thus, finding appropriate wind speed distribution is essential. Weibull distribution (WD) is the most popular distribution ...
