Robust confidence interval
WebAug 7, 2024 · A confidence interval is the mean of your estimate plus and minus the variation in that estimate. This is the range of values you expect your estimate to fall between if you redo your test, within a certain level of confidence. Confidence, in statistics, is another way to describe probability.

WebNov 27, 2016 · Usually, yes, lower confidence levels are more robust. Consider estimating a median vs. 99 percentile on a sample with 100 observations. Any single large observation is going to move 99 percentile, while median will not move a lot. I'm sure you can find a counter example, but it will look unusual. – Aksakal Nov 28, 2016 at 19:45 Add a comment
