Confidence Interval (CI) definition

Confidence Interval (CI). ’ means the statistical term for predicting, with 95 percent confidence, the bounds in which one would predict the correlation line to lie. Equations for calculating CI are provided in section 12.3(1)(ii), Equation 11–10, for the polynomial correlation and section 12.3(3)(ii), Equation 11–33, for the linear correlation. The CI as a percent of the emission limit value is calculated at the median PM CEMS response value.
