Research ArticleOpen accessIn the abstractBayesian Network Inference in Binary Logistic Regression: A Case Study of Salmonella sp Bacterial Contamination on Vannamei ShrimpPratnya Paramitha Oktaviana, Kartika FithriasariRecently binary logistic regression has been used to identify four factors or predictor variables that supposedly influence the response variable, which is testing result of Salmonella sp bacterial contamination on vannamei shrimp. Binary logistic regression analysis results that there are two predictor variables which is significantly affect the testing result of Salmonella sp bacterial contamination on vannamei shrimp, those are … …Journal of Mathematics and Statistics, Vol. 13, Issue 4 · 22 Dec 2017 · 7,667 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Comparative Assessment of Heavy Metal Pollution in Soil using pH Enrichment Factor and Pollution IndexMichael Nwachukwu, Okoro Uwaezu, Ogbuja I. Ogbuja, Leonard NwosuMany researchers have described pH as heavy metals pollution indicator in soil, but no effort has been made to determine level or quantity of heavy metals that could be indicated by pH. This study measured in-situ soil pH values at Nekede motor mechanic village against the natural background values. We used readings obtained to compute pH enrichment factor (pHeF) at … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Apr 2017 · 7,974 accessesView PDF Cite
