A multiple interval-valued linear regression model considering all the cross-relationships between the mids and spreads of the intervals has been introduced recently. A least-squares estimation of the regression parameters has been carried out by transforming a quadratic optimization problem with inequality constraints into a linear complementary problem and using Lemke’s algorithm to solve it. Due to the irrelevance of certain cross-relationships, an alternative estimation process, the LASSO (Least Absolut Shrinkage and Selection Operator), is developed. A comparative study showing the differences between the proposed estimators is provided. | URI: | https://hdl.handle.net/20.500.14279/14733 | ISSN: | 21945357 | DOI: | 10.1007/978-3-319-10765-3_22 | Rights: | © Springer International Publishing 2015. | Type: | Article | Affiliation: | University of Oviedo Cyprus University of Technology |
