bigsnpr Can 'delta' be 0?

Thank you for the great software! We have two questions about the value of 'delta':

Q1: Can 'delta' in the example code at https://privefl.github.io/bigsnpr/reference/snp_lassosum2.html be set to 0, so that lassosum2 runs without L2 regularization? q2: If the current version of lassosum2 does not accept 0 for the value of 'delta', is it possible to modify lassosum2 so that it accepts 0?

I guess it can, but it will either lead to possible divergence, or provide similar results as with e.g. delta=0.001.

Have you tried it?

Hi, sorry I have not tried it. I will let you know when I try it, hopefully in next 1-2 weeks.
