is the coefficient of association. The value approaching 1 represents a good correlation between data and regression equation. The larger the value is, the more significant the regression equation is; is the probability value of value. The smaller the value is, the more reliable the regression equation is. In summary, the regression equation is reliable for predicting concentration of chloride in concrete.
