Using Next-Generation Dna Sequence Data For Genetic Association Tests Based On Allele Counts With And Without Consideration Of Zero Inflation
(2016)
The relationship between genetic variability and individual phenotypes is usually investigated by testing for association relying on called genotypes. Allele counts obtained from next-generation sequence data could be used ...
Is There a Relationship Between Vitamin D Status and Hypocalcemia-After Total Thyroidectomy?
(Editura Acad Romane, 2016)
Context. Vitamin D plays a crucial role in calcium metabolism through parathormone-dependent process. Deficiency of this important nutrient may be associated with hypocalcemia after thyroidectomy. Objective. To evaluate ...
Modified Welch Test Statistic For Anova Under Weibull Distribution
(Hacettepe Univ, Fac Sci, 2016)
A modification to Welch test statistic is proposed to test the equality of population means of various groups under a Weibull distribution. The proposed test statistic is simple and corresponds to the standard Welch test ...
Subsymmetry and Asymmetry Models for Multiway Square Contingency Tables with Ordered Categories
(De Gruyter Open Ltd, 2016)
This paper suggests several models that describe the symmetry and asymmetry structure of each subdimension for the multiway square contingency table with ordered categories. A classical three-way categorical example is ...
The Effect of Changing Scores for Multi-Way Tables with Open-Ended Ordered Categories
(Hacettepe Univ, Fac Sci, 2016)
Log-linear models are used to analyze the contingency tables. If the variables are ordinal or interval, because the score values affect both the model significance and parameter estimates, selection of score values has ...
Robust Model Selection Criteria For Robust S And Lts Estimators
(Hacettepe Univ, Fac Sci, 2016)
Outliers and multi-collinearity often have large influence in the model/variable selection process in linear regression analysis. To investigate this combined problem of multi-collinearity and outliers, we studied and ...
Some Imputation Methods For Missing Data In Sample Surveys
(Hacettepe Univ, Fac Sci, 2016)
The present work suggests some imputation methods to deal with the problems of non-response in sample surveys. The imputation methods presented in this work lead to the precise estimation strategies of population mean. ...
