A comparative study of hybrid, neural networks and nonparametric regression models in time series prediction
(2009)
This paper presents a comparative study of the hybrid models, neural networks and nonparametric regression models in time series forecasting. The components of these hybrid models are consisting of the nonparametric ...
A Fano-Huffman based statistical coding method
(Wayne State University, 2007)
Statistical coding techniques have been used for lossless statistical data compression, applying methods such as Ordinary, Shannon, Fano, Enhanced Fano, Huffman and Shannon-Fano-Elias coding methods. A new and improved ...
Misusage of statistics in medical research
(2007)
The inappropriate use of statistical method and technique cause time and cost losts and it can be misleading to other scientific researhes. So in this study the main statistical error sources in medical research are discussed ...
Examining cronbach alpha, theta, omega reliability coefficients according to the sample size
(Wayne State University, 2007)
Differentiations according to the sample size of different reliability coefficients are examined. It is concluded that the estimates obtained by Cronbach alpha and teta coefficients are not related with the sample size, ...
Reliability and validity of Turkish version of the impact on family scale: Assessment of depressive symptoms and quality of life in mothers with cerebral palsied children
(2009)
The pragmatic aims of this study were to investigate the reliability and validity of the Turkish version of the Impact on Family Scale (IFS) and to evaluate the impact of having disabled children on mothers. Two hundred ...
A comparison study of performance measures and length of intervals in fuzzy time series by neural networks
(2009)
Deciding length of intervals and choosing performance measures have important issues to forecast fuzzy time series. Many forecasting studies accept MSE(Mean squared error) for performance measure and use only one kind of ...
A framework for fuzzy variable control charts with ?-cuts
(2007)
In traditional variable control charts, center line, upper control limit and lower control limit are crisp values. In this situation, process are defined "in control" or "out of control" with depending on observation values ...
The smoothing parameter selection problem in smoothing spline regression for different data sets
(2007)
This paper studies smoothing parameter selection problem in nonparametric regression based on smoothing spline method for different data sets. For this aim, a Monte Carlo simulation study was performed. This simulation ...
A semiparametric additive regression model: Investigation of house price in Eskisehir (Turkey)
(2007)
In this paper, different regression models are obtained to examine relation between house price and house features in Centrum of Eskisehir Province (Turkey). The statistical analyses of this paper indicate that some of ...
Estimating variances inweighted least-squares estimation of distributional parameters
(Association for Scientific Research, 2016)
Many estimation methods have been proposed for the parameters of statistical distribution. The least squares estimation method, based on a regression model or probability plot, is frequently used by practitioners since its ...
