Confidence interval for the slope

Confidence Interval For The Slope. The 95 confidence interval for the slope is the estimated coefficient 70595 two standard errors 09776. This confidence interval follows the same general form that we have been using. This can be computed using confint. The slope β 1 and its associated 90 confidence interval CI were compared to the reference interval with a ratio of maximal to minimal dose r 8 and lower and upper acceptance limits.
