A New Improved Estimator of Population Mean in Partial Additive Randomized Response Models
(Hacettepe Univ, Fac Sci, 2017)In this study, we have developed a new improved estimator for the population mean estimation of the sensitive study variable in Partial Additive Randomized Response Models (RRMs) using two non-sensitive auxiliary variables. ... -
A New Multilayer Feedforward Network Based on Trimmed Mean Neuron Model
(Acad Sciences Czech Republic, Inst Computer Science, 2015)The multilayer perceptron model has been suggested as an alternative to conventional approaches, and can accurately forecast time series. Additionally, several novel artificial neural network models have been proposed as ... -
A New Proposed Model of Restricted Data Envelopment Analysis By Correlation Coefficients
(Elsevier Science Inc, 2013)The concept of efficiency in data envelopment analysis (DEA) is defined as weighted sum of outputs/weighted sum of inputs. In order to calculate the maximum efficiency score, each decision making unit (DMU)'s inputs and ... -
A New Uniform Distribution With Bathtub-Shaped Failure Rate With Simulation And Application
(2019)Bathtub failure rate shape is widely used in industrial and medical applications. In this paper, a three-parameter lifetime distribution, so-called the generalized Weibull uniform distribution that extends the Weibull ... -
A Regression Type Estimator For Mean Estimation Under Ranked Set Sampling Alongside The Sensitivity Issue
(2019)Koyuncu and Kadilar [7] introduced a family of estimators under simple random sampling. In this article; we adapt these estimators for ranked set sampling. Further, we suggest a regression-type estimator of population mean ... -
A84 Updated Systematic Review With Network Metaanalysis On Comparative Efficacy And Tolerability Of Different Intravenous Iron Products For The Treatment Of Iron Deficiency Anemia In Patients With Ibd
(2019)Background In patients with inflammatory bowel disease (IBD), iron deficiency anemia (IDA) is a frequent complication. Causes include intestinal bleeding, reduced iron intake and impaired duodenal iron absorption due to ... -
Almost Unbiased Estimation Procedures Of Population Mean In Two-Occasion Successive Sampling
(Hacettepe Univ, Fac Sci, 2018)The objective of this paper is to construct some unbiased estimators of the current population mean in two-occasion successive sampling. Utilizing the readily available information on an auxiliary variable on both occasions, ... -
An Arma Type Fuzzy Time Series Forecasting Method Based On Particle Swarm Optimization
(Hindawi Ltd, 2013)In the literature, fuzzy time series forecasting models generally include fuzzy lagged variables. Thus, these fuzzy time series models have only autoregressive structure. Using such fuzzy time series models can cause ... -
ANOVA Modellerinde Kareler Toplamı Yöntemlerinin Karşılaştırılması
(Kafkas Univ, Veteriner Fakultesi Dergisi, 2009)The total sum of squares in ANOVA models is decomposed and the significances of the main term and interaction terms are tested. The four different methods called as Type I, II, III, and IV are used for calculating the sum ... -
Aralıklı Durdurulmuş Veriler ile Yaşam Çözümlemesi
(Fen Bilimleri Enstitüsü, 2019)Censoring is the most important feature that distinguishes survival analysis from other statistical methods. Censored observation means incomplete observation and provides partial information about the time of failure. ... -
ARDL Model Bounds Test Approach: The Case of Turkey
(Fen Bilimleri Enstitüsü, 2017)In the econometric literature, ARDL bounds testing approach proposed by Pesaran and Shin [16], improved Pesaran et al. [17], and Toda-Yamamoto causality procedures [12] are widely used in empirical analysis because the ... -
Ardışık Olasılık Oran Testine Dayalı Kontrol Kartları
(Fen Bilimleri Enstitüsü, 2013)In statistical process controls, control cards are very important tools for testing statistically if the process is in control or not and evaluating the production process. Sequential probability test is a well-known method ... -
Autocorrelation Corrected Standard Error For Two Sample T-Test Under Serial Dependence
(Hacettepe Univ, Fac Sci, 2017)The classical two-sample t-test assumes that observations are independent. A violation of this assumption could lead to inaccurate results and incorrectly analyzing data leads to erroneous statistical inferences. However, ...
