# How do I go about asking this question here on Stats.SE?

Total newb to stats: I'm an embedded programmer with a BSEE, so I like to think I've got lots of knowledge with the least possible amount of applicability to real life.

I built a test bench to observe the output of a sensor and came up with an algorithm to quantify an anomaly I observed in the data. I wanted to know what to call it, so I asked on Math.SE what is the average of an integral. While continuing to research related questions on Math.SE for a week, I just saw someone said their similar-ish question was answered on here...

Could I please get help with which tags to use to post the Math.SE question on here? Or if this is really trivial, I'd appreciate a pat on the back and "it is $__________$, duh!" for an answer.

Note that in the stackoverflow alagorithm link above, I mention that standard deviation, skewness, nor Kurtosis help. Also that I have known data, so my problem isn't helped with estimation tools like linear regression.

Basically, I came up with a way to quantify the "dip" in this figure and want to know what that process is called:

• This question is fine for the main site. For a tag I would suggest quality-control given the nature of the objective. – Andy W Oct 31 '13 at 12:47
• There are other statistical applications that calculate statistics for areas in vaguely similar plots (e.g. GINI Coefficient, ROC curves), but it isn't obvious to me that you need to work with the area at all. Just evaluating deviations from expected may be sufficient to identify problematic sensors. – Andy W Oct 31 '13 at 12:48
• Hi, Chris. I agree with @Andy that this would be fine for the main site. It could even undergo a slight tweak to open the door to other suggestions on solutions. You've put an admirable and impressive amount of work both into the test setup and your question! If you'd like the question moved here, please flag it on the main math.SE site, choose "other", and ask them to migrate it to stats.SE. Cheers. – cardinal Oct 31 '13 at 14:01
• @cardinal thank you (and Andy) for the suggestion; I'll do that. Also please explain more on how to "open the door". Thanks! – Chris K Oct 31 '13 at 19:41
• @ChrisK: I've migrated your question to Cross Validated. please go ahead and edit it w.r.t. the above suggestions! stats.stackexchange.com/questions/74306/… – Willie Wong Nov 1 '13 at 11:33
