Outlier analysis is about finding the values that look like they do not belong with the rest of the values. Put simply, outliers are extreme values that greatly differ from the other observations. A good book on outlier analysis is Outlier Analysis, 2nd Edition, by Charu C. Aggarwal (Springer, 2017).

The outlier technique that is going to be implemented in outlier.go, which is going to be presented in four parts, is based on standard deviation. You will learn more about this technique later.

The first part of outlier.go is as follows:

package main 
import ( 

The technique that is going to be implemented requires packages of the standard Go library only.

The second...
