The other answers are very helpful; just a couple of things to add that are a bit more than a comment.
First, if part of the problem is that you are having trouble getting free (unpaid) access to papers, peer-reviewed journal articles based on work supported by the US National Institutes of Health (NIH) must now be made freely available within 12 months of publication. NIH supports some biostatistics research and a lot of applied work, so you can find such papers via the PubMed website. I just did a search there for "regression methods," sorted by "Relevance," and the top hit was a comparison of penalized regression methods that is available as a "Free PMC Article." Haven't read the paper so I won't comment on quality, but you do need to read some lower-quality papers in any event to appreciate the differences. So add PubMed to Google Scholar or arXiv as recommended by @Aksakal.
Second, consider trying to answer more questions on this site (if you have a strong interest in statistics) or on another StackExchange site if another site is more aligned with your interests. I've already written a fair number of scientific papers, yet I've found that the discipline developed by trying to write brief, intelligible answers here still helps me a lot.
