Expert Testimony: Regression Analysis and Other Systematic Methodologies (Guardian Pipeline, L.L.C. V. 950.80 Acres of Land) (Case Overview‪)‬

The Seventh Circuit's Guardian Pipeline decision encourages wider use of multiple regression analysis in valuation proceedings in place of the longstanding matched pair comparison canon. This article reviews applicable evidentiary rules, providing details on cases appraisers often hear cited but may not know well, such as Daubert and Kumho, and on Federal Rule of Evidence 702. A well-designed regression model would seem to meet all requirements for admissibility imposed by federal rules and case law, and by state rules favoring systematic analysis. Yet other techniques also might meet those requirements. **********
