Adaptive kernel density estimation with generalized least square cross-validation
Demir, Serdar (Hacettepe Univ, Fac Sci, 2019)Adaptive kernel density estimator is an efficient estimator when the density to be estimated has long tail or multi-mode. They use varying bandwidths at each observation point by adapting a fixed bandwidth for data. It is ... -
Adaptive Weighted Performance Criterion for Artificial Neural Networks
Bal, Çağatay; Demir, Serdar (Ieee, 2018)Extended Weighted Performance Criterion (EWPC) which is motivated from Weighted Information Criterion (WIC) has been shown promising results in previous study and results of the application showed that EWPC is capable of ... -
Blood and Milk Beta-hydroxybutyric Acid Concentrations in Different Dairy Cattle Breeds and Association of Subclinical Ketosis with Postpartum Health Disorders, Culling Rate, Body Condition Score, Parity and Milk Production in Holstein
Aksoy, Kemal; Deniz, Abdülkerim; Demir, Serdar; Onmaz, Ali Cesur (KAFKAS UNIV, 2022)The aim of the study was to analyse beta-hydroxybutyric acid concentration in the blood (BBAC) and milk (MBAC) at postpartum week 2 (PPW2) and week 4 (PPW4) in Holstein (n=216, 8 farms), Montbeliard (n=23), Simmental (n=38) ... -
Credibility Using Semiparametric Models With Adaptive Kernel
Mert, Mehmet; Demir, Serdar (Gazi Univ, 2013)The goal of credibility theory is to estimate the future claim of a given risk. The most accurate estimator is predictive mean. If the conditional mean of losses given the risk parameter and the prior distribution of the ... -
Criteria for Best Architecture Selection in Artificial Neural Networks
Bal, Çağatay; Demir, Serdar (World Scientific Publishing Co., 2022)Architecture selection in artificial neural networks is a critical process which determines a satisfactory neural network model(s) that will lead to the most accurate results. The architecture that minimizes the difference ... -
EFFECTS OF MAGNESIUM AND CALCIUM CATIONS ON BIOFILM FORMATION BY Sphingomonas paucimobilis FROM AN INDUSTRIAL ENVIRONMENT
Güvensen, Nur Ceyhan; Demir, Serdar; Özdemir, Güven (Parlar Scientific Publications (P S P), 2012)Bacterial biofilms may form on all surface-associated natural and many industrial environments. Biofilm formation requires particular notice due to its associated risks for human health and its impact on environmental ... -
Forecasting COVID19 Reliability of the Countries by Using Non-Homogeneous Poisson Process Models
Güler Dinçer, Nevin; Demir, Serdar; Yalçın, Muhammet Oğuzhan (Springer, 2022)Reliability is the probability that a system or a product fulfills its intended function without failure over a period of time and it is generally used to determine the reliability, release and testing stop time of the ... -
Forecasting TRY/USD Exchange Rate with Various Artificial Neural Network Models
Bal, Çağatay; Demir, Serdar (Assoc Information Communication Technology Education & Science, 2017)Exchange rate forecasting is one of the most common subjects among the forecasting problem field. Researchers and academicians from many different disciplines proposed various approaches for better exchange rate forecasting. ... -
Fuzzy panel data analysis
Yalçın, Muhammet Oğuzhan; Güler Dinçer, Nevin; Demir, Serdar (University of Kuwait, 2021)In statistical and econometric researches, three types of data are mostly used as cross-section, time series and panel data. Cross-section data are obtained by collecting the observations related to the same variables of ... -
ON THE ADAPTIVE NADARAYA-WATSON KERNEL REGRESSION ESTIMATORS
Demir, Serdar; Toktamış, Oniz (Hacettepe Univ, Fac Sci, 2010)Nonparametric kernel estimators are widely used in many research areas of statistics. An important nonparametric kernel estimator of a regression function is the Nadaraya-Watson kernel regression estimator which is often ... -
Testing the Psychometric Properties of the Scale of Ethnocultural Empathy in Turkey
Ozdikmenli-Demir, Gozde; Demir, Serdar (Routledge Journals, Taylor & Francis Ltd, 2014)The validity and reliability of the Scale of Ethnocultural Empathy (SEE) was tested using a sample of 348 emerging adult university students living in Turkey. Different from the original scale's four-factor structure, ...
