Estimation of the $l_{2}$ -norm and testing in sparse linear regression with unknown variance

Alexandra Carpentier, Olivier Collier, Laetitia Comminges +2

We consider the related problems of estimating the $l_{2}$ -norm and the squared $l_{2}$ -norm in sparse linear regression with unknown variance, as well as the problem of testing the hy…
