We devise methods for estimating the parameters of a prospective logistic model with dichotomous response D and arbitrary covariates X from case-control data when these covariates are measured with error. We suppose that some fraction of the cases and controls provide only the error-prone covariate measurements, W (the "incomplete" or "reduced" data), whereas some of the cases and controls provide measurements on X and W (the "complete" data). We assume a measurement error density with a finite set of parameters a, namely fwlxD(wlx, d, a), and nondifferential misclassification is treated as a special case of this model, fwlx(wlx, a). One algorithm estimates a and a needed distribution functi...

Water is one of the most precious and basic needs of life for all living beings, and a precious national asset. Without it, the existence of life cannot be imagined. Availability of pure water is decreasing day by day, and water scarcity has become a major problem that is faced by our society for the past few years. Hence, it is essential to find and disseminate the key solutions for water quality and scarcity issues. The inaccessibility and poor water quality continue to pose a major threat to human health worldwide. Around billions of people lacking to access drinkable water. The water contains the pathogenic impurities; which are responsible for water-borne diseases. The concept of water ...
