Confidence Interval and Prediction Intervalold memories/physics 2007.06.20 06:35
Confidence Interval (CI) describes the uncertainty in $\bar Y$ as an estimate of $\mu$, where $\bar Y$ is the sample mean and $\mu$ the population(true) mean 95% CI means that the true mean value will be inside this interval with 95% probabilitySuppose repeated samples of Y_i are taken of the same size and at the same fixed values of X as were used to determine the fitted line above. Then of all..
