Furthermore, with > Stellar, we can capture statistical summaries. We should provide rudimentary > outlier detection functionality in the form of Stellar functions that can > operate on captured state from the profiler. > To begin, we should enable simple outlier tests using distance from a central > measure such as Median Absolute Deviation (see > http://www.itl.nist.gov/div898/handbook/eda/section3/eda35h.htm). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
