We consider the application of a popular penalised regression method, Ridge Regression, to data with very high dimensions and many more covariates than observations. Our motivation is the problem of out-of-sample prediction and the setting is high-density genotype data from a genome-wide association or resequencing study. Ridge regression has previously been shown to offer improved performance ...
Background: It is well recognized that an increased body weight is often associated with increased blood pressure. Moreover, leptin an adipocyte-derived hormone is strongly suggested to have an important role in pathogenesis of the obesity. We aimed to evaluate the levels of serum leptin in association with obesity and hypertension in a sample of Iranian obese children. Methods: Children from...
The findings of theoretical investigations indicate that short-term auditor tenures may contribute to further audit report lags (ARLs). On the other hand, auditor industry expertise represents one of the determinant factors contributing to audit quality, which has been widely studied in numerous researches. Indeed, the better the quality of audit, the less delayed would be the audit report. As ...
Apart from the international comparative data and analysis that International Association for the Evaluation of Educational Achievement (IEA) studies traditionally provide, there is also an opportunity for countries to include national options that may enrich a country’s knowledge in a focus area. This paper reports on research that was conducted by including a national option in IEA’s TIMSS’99...
conclusions our research determined an association between screen time, physical activity and rbmi. screen time was a prominent predictor of rbmi in children. it is important for health workers to decrease screen time of children to prevent the prevalence of being overweight and obesity. patients and methods in this cross sectional descriptive study we randomly selected 302 students, from all d...
In recent years, there have been increasing efforts in applying association rule mining to build Associative Classification (AC) models. However, the similar area that applies association rule mining to build Associative Regression (AR) models has not been well explored. In this work, we fill this gap by presenting a novel regression model based on association rules called AREM. AREM starts wit...
Objective(s): To investigate the association of single nucleotide polymorphisms (SNPs) in the peroxisome proliferator-activated receptors gamma (PPARG) with essential hypertension (EH) and additional role of gene– high-density lipoprotein cholesterol (HDL) interaction. Materials and Methods:A total of 1640 patients with EH (806 males, 834 females), with a mean age of 52.5±12.6 years, were selec...
Background: Industrialization and urbanization had a devastating impact on public health and caused an increase in health related morbidity and mortality. In fact, asthma is a chronic condition which is considered as one of the significant challenges of public health. In this study, we investigated the association of air pollution and weather conditions with excess emergency ward admissions o...
Background: Helicobacter pylori has been classified as the class I carcinogenic agent by world health organization. Colonization of the human stomach with H. pylori is a risk factor for gastroduodenal diseases. The secreted vacA toxin is an important H. pylori virulence factor that causes multiple alterations in gastric epithelial cells and T cells. Several families of vacA alleles have been de...
