AIM The aim of this study was to determine whether there is relation between body mass index and symptoms of gastro-esophageal reflux disease in our community using Logit, Probit and Complementary log-log models. BACKGROUND The most frequent statistical tool to address the relationship among a dichotomous response and other covariates is logistic regression. However logistic regression is fam...

introduction: food consumption patterns are changing as a result of health and environmental issues. subsequently, farmers are under increasing pressure to develop and utilize less toxic production methods and pest control. organic agriculture is a production system that sustains the health of soils, ecosystems, and people. it relies on ecological processes, biodiversity, and cycles adapted to ...

A fast and simple method is proposed that produces approximate multivariate local D-optimal designs of high e¢ ciency for models with binary response. The method assumes availability of a D-optimal design for a parallel normal response linear problem that has the same linear predictor, with an assumption of homogenous variance; the change required to transform the standard design into an e¢ cie...

The main objective of the study is investigating impact production risks on adoption improved technologies (such as seed, inorganic fertilizer and chemical inputs) level multiple in Ethiopia particularly Amhara region. used two years cross sectional data collected 2011 2013. applied stage regression analysis, first, I regressed function order to drive expected output risk factors (variance skew...

Inferring concerted changes among biological traits along an evolutionary history remains important yet challenging problem. Besides adjusting for spurious correlation induced from the shared history, task also requires sufficient flexibility and computational efficiency to incorporate multiple continuous discrete as data size increases. To accomplish this, we jointly model mixed-type by assumi...
