An evaluation of a novel approach for clustering genes with dissimilar replicates
Cinar, Ozan; İyigün, Cem; İlk Dağ, Özlem (Informa UK Limited, 2020-12-01)
Clustering the genes is a step in microarray studies which demands several considerations. First, the expression levels can be collected as time-series which should be accounted for appropriately. Furthermore, genes may be...
Effect of FMD vaccination schedule of dams on the level and duration of maternally derived antibodies
Sareyyupoglu, B.; Gulyaz, V.; Cokcaliskan, C.; Unal, Y.; Cokulgen, T.; Uzunlu, E.; Gurcan, S.; İlk Dağ, Özlem (Elsevier BV, 2019-11-01)
Vaccination against Foot and Mouth Disease (FMD) in pregnant cows is crucial to produce greater immunity in new born calves, especially in late gestation, as this directly affects neonatal immunity. Therefore, we aimed to ...
A marginalized multilevel model for bivariate longitudinal binary data
Inan, Gul; İlk Dağ, Özlem (Springer Science and Business Media LLC, 2019-06-01)
This study considers analysis of bivariate longitudinal binary data. We propose a model based on marginalized multilevel model framework. The proposed model consists of two levels such that the first level associates the m...

Clustering of short time-course gene expression data with dissimilar replicates
Cinar, Ozan; İlk Dağ, Özlem; İyigün, Cem (2018-04-01)
Microarrays are used in genetics and medicine to examine large numbers of genes simultaneously through their expression levels under any condition such as a disease of interest. The information from these experiments can b...
A Categorical Principal Component Regression on Computer-Assisted Instruction in Probability Domain
Kapucu, Tuğba; İlk Dağ, Özlem; Batmaz, İnci (2018-01-01)
The purpose of this study is to examine the effects of computer-assisted instructional material (CAIM) prepared in R program on eighth grade students’ permutation–combination and probability achievement and their attitudes...
Predicting intraoperative pain in emergency endodontic patients: clinical study
Yucel, Olga; Ekici, Mugem Asli; İlk Dağ, Özlem; İLHAN, MUSTAFA NECMİ; KAYAOĞLU, GÜVEN (2018-01-01)
This prospective observational study sought to investigate the incidence of intraoperative pain (IOP) among emergency endodontic patients and to construct an IOP prediction model that includes preoperative pain level (PPL)...
Asymmetric Confidence Interval with Box-Cox Transformation in R
Dağ, Osman; İlk Dağ, Özlem (null; 2017-12-08)
Normal distribution is important in statistical literature since most of the statistical methods are based on normal distribution such as t-test, analysis of variance and regression analysis. However, it is difficult to sa...
Box-Cox Transformation for Linear Models via Goodness-of-Fit Tests in R
Dağ, Osman; İlk Dağ, Özlem (null; 2017-12-08)
Sporadik Kolorektal Kanser ile İlişkilendirilmiş Aday Tekli Nükleotid Polimorfizmlerinin Türk Popülasyonu için Değerlendirilmesi
