I am trying to put into words a concept that is not in my area of expertise.
What area of knowledge concerns itself with the following?
Specifics will be appreciated and the best, rewarded.
I am collecting daily data on many differant metrics (numbers, measures).
I am seeing how much the current measure varies from the average, as indicator of a deviation from the norm, but it is not satisfactory.
I am envisioning computer screen with a slider control which will show:
all data....sliding up to highly anomalous data only.
I want to be alerted to anomalous trends.
How should anomalous be defined?
What about filtering data-errors?
What differentiates a data-anomaly and a data-error?
Thanks for your input
