WebWhen the output data set doesn’t contain any variable to identify for which level of the variable these CI’s are computed there is higher probability/chance that one considers the CI calculated by Proc Freq as the one for Partial Respondents where it is actually NOT. One needs to be really careful while using this feature of Proc Freq. WebThis worked. I backsolved for SE using 89.63 + - t(0.95,43)xSE = Lower Bound where Lower Bound was 87.28 for the CI and 74.46 for the PI. The SE CI was 1.39 and SE PI was 9.02. So the SE for the prediction interval IS greater than the confidence interval.
