MLR and ANN models of significant wave height on the west coast of India
(Pergamon-Elsevier Science LTD, 2012)Multiple linear regression (MLR) and artificial neural network (ANN) models are used in the present work to describe the significant wave height off Goa, located in the west Indian coast. A comparison study was carried out ... -
Biplots of fuzzy coded data
(Elsevier Science BV, 2011)A biplot, which is the multivariate generalization of the two-variable scatterplot, can be used to visualize the results of many multivariate techniques, especially those that are based on the singular value decomposition. ... -
One-step M-estimators: Jones and Faddy's skewed t-distribution
(Taylor & Francis LTD, 2013)One-step M (OSM)-estimator needs some initial/preliminary estimates at the beginning of the calculation process. In this study, we propose to use new initial estimates for the calculation of the OSM-estimator. We consider ... -
A new approach for estimating the parameters of Weibull distribution via particle swarm optimization: An application to the strengths of glass fibre Cheek tor data
(Elsevier Sci LTD, 2019)Three-parameter Weibull is one of the most popular and most widely-used distribution in many fields of science. Therefore, many studies have been conducted concerning the statistical inferences of the parameters of Weibull ... -
Robust factorial ANCOVA with LTS error distributions
(Hacettepe University, Fac Sci, 2018)In this study, parameter estimation and hypotheses testing in the balanced factorial analysis of covariance (ANCOVA) model, when the distribution of error terms is long-tailed symmetric (LTS) are considered. The unknown ... -
Generalized Lindley and Power Lindley distributions for modeling the wind speed data
(Pergamon-Elsevier Science LTD, 2017)In this study, we propose to use Generalized Lindley (GL) and Power Lindley (PL) distributions as an alternative to the Weibull distribution for modeling the wind speed data. In the application part of the study, we consider ... -
Inferences on stress-strength reliability based on ranked set sampling data in case of Lindley distribution
(Taylor & Francis LTD, 2018)In this study, we consider point and interval estimation of stress-strength reliability R = P(X < Y) based on ranked set sampling when the distribution of the stress and the strength are both Lindley. Firstly, maximum ... -
Interval estimation of the system reliability for Weibull distribution based on ranked set sampling data
(Hacettepe University, Fac Sci, 2018)Inference for the system reliability R is one of the most popular problems in the areas of engineering, statistics, biostatistics and etc. Therefore, there exist considerable numbers of studies concerning this problem. ... -
A new weighted distribution as an extension of the generalized half-normal distribution with applications
(Taylor & Francis LTD, 2018)In this study, a new extension of generalized half-normal (GHN) distribution is introduced. Since this new distribution can be viewed as weighted version of GHN distribution, it is called as weighted generalized half-normal ... -
Ridge-Type MML Estimator in the Linear Regression Model
(Springer International Publishing Ag, 2019)Ridge regression is widely used to deal with the multicollinearity problem. However, traditional ridge estimator (Hoerl and Kennard 1970) loses its efficiency in the presence of outliers, since it is obtained based on least ...
