It addresses the problem of robust linear regression for statisticians and data analysts, but appears incremental as it builds on existing L1 approximation techniques.
The report introduces methods for computing L1 straight-line fits to data, focusing on explaining L1 approximation properties for newcomers and detailing algorithms for experts.
The initial remarks in this technical report are primarily for those not familiar with the properties of L1 approximation, but the remainder of the report should also interest readers who are already acquainted with the inner workings of L1 algorithms.
