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 ... -
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, ... -
Bayesian Estimation of Order-Restricted and Unrestricted Association Models
(Elsevier Inc, 2013)Association models include score parameters to multiplicatively represent the hierarchy between the levels of the considered ordinal factor. If order restrictions are placed on the scores, an estimation problem becomes a ... -
