Do you think it might also be an option to calculate the variance covariance matrix from the Fisher information matrix calculated for the selected variables, and repeat this procedure for...
@Mamba413 No I haven't seen this exact method being used - perhaps mainly because until recently we didn't have access to good L0 penalized GLM fitting engines.... But it would...
No worries - I have some bioinformatics master students working on this exact topic to figure out what approach would or would not work... I'll let you know once we...
Many thanks for that - that's very helpful! And glad `abess `correctly takes into account the weight matrix for identity link Poisson. For the problem with Gaussian noise I also...
Well I was asking these questions also partly to compare the solution quality of `abess` with that of my own `L0glm `package that I was developing - that one uses...
In this particular example, my variables are not independent, and yet clipping still seemed to perform very well to recover the true solution. In fact, `osqp`, where hard nonnegativity constraints...
Ha that's very cool - many thanks for that! Looking forward to that! Did that result in good performance for this problem then, not only in terms of speed, but...
Many thanks - that sounds really promising - thanks for your work on this! My iterative adaptive ridge method took half a minute for that problem size (currently finishing up...
Many thanks for this! Today I was just testing with the latest version on CRAN (abess_0.4.8) but I am still running into a couple of problems - here a multitask...
