Estimation of the -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 -norm and the squared -norm in sparse linear regression with unknown variance, as well as the problem of testing the hy…

Minimax rate of testing in sparse linear regression
Alexandra Carpentier, Olivier Collier, Laëtitia Comminges +2
We consider the problem of testing the hypothesis that the parameter of linear regression model is 0 against an s-sparse alternative separated from 0 in the l2-distance. We show th…
