Factors that influence the pH of water through the application of linear regression models
Main Article Content
Abstract
In this article, some factors that could alter the pH of the Chimbo river water , which is located in the province of Bolivar in Ecuador are evaluated. The methodology to be used is of Multiple linear Regression, emphasizing the coefficient of determination R2 adjusted under the criteria of normality. Results for the different statistical models analyzed under free software "R" are exposed and contrasted and their information is discussed for the study of water quality based on its pH. Finally, it establishes that the variables that most influence the pH are the alkalinity, sulfate, and chloride present in the water and we show some predictions of the pH of the water on the basis of the best model obtained.
