A simulation study with different number of observation using nonparametric regression splines
(2011)In this study we made a simulation study using various nonparametric techniques. The methods that we have used in this study are following: regression spline, penalized spline, and their Bayesian versions: adaptive Bayesian ... -
Forecasting neural network-based fuzzy time series with different neural network models
(2011)Fuzzy approach and artificial neural networks become effective tool for researchers by forecasting fuzzy time series. The relation of these has advantage to improve forecasting performance especially in handling nonlinear ... -
On developed estimation methods via unique and multiple parametrization
(2012)In the present study, two methods, based on entropy optimization principle, to estimate missing (or forecasting) values in the given time series are suggested. In the first method successively replaces the missing values ... -
Optimum smoothing parameter selection for penalized least squares in form of linear mixed effect models
(Taylor & Francis LTD, 2012)In this article, we discuss the penalized least squares problem which has many advantageous computational properties. This method based on penalized spline (P-spline) smoothing can be formulated to fit into a linear mixed ... -
Estimator based on percentiles for log-logistic distribution
(2012)In this study, we consider the estimator based on percentiles for log-logistic distribution similar to the study of [6] and we also graph breakdown plots of the estimators that are considered below to have an opinion about ... -
Survival Data Analysis By Generalized Entropy Optimization Methods
(Melandrium, 2013)Entropy Optimization Methods (EOM) have important applications, especially in statistics, economy, engineering and etc. There are several examples in the literature that known statistical distributions do not conform to ... -
Spatial Analysis of Unemployment Rate with Literacy Rate and Socioeconomic Development Index for cities of Turkey
(Int Business Information Management Assoc-Ibima, 2015)The objective of the study is to investigate the spatial pattern of unemployment rate with socio economic development index (SDI) and literacy rate for 81 cities of Turkey and also the spatial correlation between these ... -
Spatial analysis of unemployment rate with literacy rate and socioeconomic development index for cities of Turkey
(International Business Information Management Association, IBIMA, 2015)The objective of the study is to investigate the spatial pattern of unemployment rate with socio economic development index (SDI) and literacy rate for 81 cities of Turkey and also the spatial correlation between these ... -
Analysis of the modified weibull distribution for estimation of wind speed distribution
(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 ... -
Evaluation of robust estimation methods in estimating weibull parameters for wind energy application
(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 ... -
Distributions of Wind Speed at Different Heights
(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 ... -
A Statistical Investigation on Wind Energy Potential of Northwest of Turkey
(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. ... -
The theoretical structure of Fuzzy Analytic Network Process (FANP) with Interval Type-2 Fuzzy Sets
(Elsevier Science BV, 2016)The Fuzzy Analytic Network Process has solved multi-criteria decision making problems. Type-1 fuzzy sets used defining as expert's linguistic judgement because fuzzy set theory is concerned with uncertainty in human thought ... -
A statistical investigation on wind energy potential of Northwest of Turkey
(Institute of Electrical and Electronics Engineers Inc., 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. ...
