Alternatively, you can use the confidence interval to interpret an odds ratio and draw the same conclusions as using the p-value. If your CI excludes 1, your results are significant. However, if your CI includes
Simulations indicate that the Satterthwaite approximation used by PROC MIXED results in highly inflated confidence interval lengths, while the interval lengths from the other procedures are usually similar but also biased upward. The coverage rates of the confidence limits from all four procedures appear...
We can calculate what sample size we will need in order for our confidence interval to have a certain margin of error.Figure 1. On the verbal section of the SAT, the standard deviation is known to be 100. What size sample would we need to construct a 95% confidence interval with a ...
