http://parker.ad.siu.edu/Olive/rch4.pdf In statistics, generalized least squares (GLS) is a technique for estimating the unknown parameters in a linear regression model when there is a certain degree of correlation between the residuals in a regression model. In these cases, ordinary least squares and weighted least squares can be … See more In standard linear regression models we observe data $${\displaystyle \{y_{i},x_{ij}\}_{i=1,\dots ,n,j=2,\dots ,k}}$$ on n statistical units.

In spite of this, it is highly affected by the presence of observations too much different from all the rest. These are known as atypical observations or outliers.
