Irregular longitudinal data analysis with statistical and machine learning methods for hazardous asteroids Tanrıverdi, İrem; İlk Dağ, Özlem; Gürkan, Mehmet Atakan (2024-04-01) Observations of the asteroids have been performed as long as it has been feasible by the available observational equipment. Recorded data, going back to 18th century, allowed a classification of these celestial objects’ ha...
GeneSelectML: a comprehensive way of gene selection for RNA-Seq data via machine learning algorithms DAĞ, OSMAN; KAŞIKCI ÇAVDAR, MERVE; İlk Dağ, Özlem; Yesiltepe, Metin (2022-11-01) Selection of differentially expressed genes (DEGs) is a vital process to discover the causes of diseases. It has been shown that modelling of genomics data by considering relation among genes increases the predictive perfo...
R Yazılımına Giriş, 3. baskı İlk Dağ, Özlem (Detay Yayıncılık, 2021-02-01) R nedir ve neden öğrenmeliyim?Ücretsiz ve ticari amaç gütmeyen bir program olan R'ın ilk sürümü 2000 yılı başlarında yapılmış, bu tarihten itibaren hızla yayılmış ve kendine büyük bir kullanıcı ve hatta hayran kitlesi yara...
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...
Investigation of seven european colorectal cancer related SNPs in Turkish sporadic colorectal cancer population Cumaogullari, O.; İlk Dağ, Özlem; Rajabli, F.; Kuzu, A.; ÖZDAĞ, Hilal (2018-07-01)
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...
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)...
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...
