The literature has recently devoted close attention to error-prone variables. Nevertheless, only a small number of research have considered measurement error in spatial econometric models. The presence of measurement error in the spatial econometric models needs to be considered as a result of the rise in spatial data analysis, as the relationship...

There are various models that allow the spatial autocorrelation between observations to be considered in modeling. However, it is seen that the effects of measurement errors in both the response and explanatory-variables on the unknown parameters of these models have not been adequately investigated. In this study, within the framework of spatial l...

The multicollinearity and error-prone variables in linear regression models cause problems in parameter estimation in that they both impair the estimation and statistical analysis. Consideration of both problems simultaneously has shown that the error-prone variables mask the multicollinearity. The variance inflation factor has been proven to be th...

The present study aims to determine the relevant variables for the scores obtained from alcohol addiction, internet addiction, e-bullying, and e-victimization scales of smoking-addictive university students and to investigate the possible correlations between the scales. The study group consists of 300 students who declared that they smoked at leas...

In the literature, the response and explanatory variables examine over the observations and random errors that arise during the observation process. The variables that cannot exactly measure are called error-in-variables and are analyzed with measurement errors models. Besides some variables are not measurable directly with a measurement unit due t...

One of the important assumptions of the classical regression analysis is homoscedasticity. It simplifies the standard error formulas of the ordinary least square (OLS) estimators and ensures that these estima-tors are efficient among the other linear estimators. Heteroskedastic errors disturb the efficiency properties of the OLS estimators and the...

Doğrusal regresyon analizinde, açıklayıcı değişkenler hata ile ölçüldüğünde regresyon parametreleri sapmalı tahmin edilmektedir. Sapmalı tahminler ise yanlış sonuç çıkarımları yapmaya, değişkenler arası ilişki yapısını bozmaya ve kestirimlerin sapmalı olması gibi sonuçlara neden olmaktadır. Ölçüm hatasına sahip açıklayıcı değişkenin olduğu bu tip m...

The casual relations among the variables of interest may be directed or transmitted by the other variable or variables. The standard mediation analysis including a series of linear regressions is used to estimate these casual direct/indirect relationships among the variables. It is well documented that the ordinary least square (OLS) estimators are...

Nowadays, both measurement errors and chaotic structures in data are frequently included in the literature. The main reasons for this are biased parameter estimations in the presence of measurement error and the unpredictability of chaotic structures. Although it has been investigated whether the confusion in the data is due to the measurement erro...
