Hi,
I am trying to implement Group Lasso using 'grplasso' package.I am facing trouble finding the lambda value(penalty parameter).There is a function 'lambdamax',which provides a value of lambda,which I am not sure how it is calculated and is giving me incorrect results(when I tried implementing it blindly).An ideal case would be to cross validate to find the least penalty value,but is not available on the package.Any help on this would be great.Thanks,
