Abstract

Regression widely used for prediction and forecasting a number of applications with function. Regression analysis estimates the uncertain expectation of according to the defined variables the independent variables. Regression is used to understand the relationships between the variables and arguments relating to the use survey. Overall, the regression variables defined by conditional expectation beam of argument-that the variable is normally the least resolved the disagreement; Focal points in the distribution parameters or arguments temporary variables. In Sindh University hostels the following experiment was conducted on Rotating Biological contactor through different parameters such as retention time and multiple numbers of disks. Experiment shows the removal on different retention time levels i-e; 2 hours, 2.5 hours and 3 hours with multiple number of disks of Biological Oxygen Demand (BOD). “r” indicates that there is a positive correlation in between the influent and effluent figures, where as the co-efficient of determination (r2) indicates (when multiply by 100) the reliability of effluent on influent data. Co-efficient of determination (r2) also indicates that the regression equations are how much reliable for the estimation.
