If you mean the code, then yes, it is on GitHub and CRAN. The latest versions are always on GitHub. But CRAN (the source for R packages) doesn't allow me to do updates more than about once every 2 months. The latest earthUI is on CRAN, but I am in the process of preparing glmnetUI and mgcvUI for CRAN (by the end of another 7 days). - although the latest versions are always on GitHub. The CRAN version is always tested on Windows, Linux, and MacOS. But not GitHub (not that they won't work ... but I do updates on GitHub 3-6 times/week and simply don't have time to do full UI testing on each OS before committing changes). These packages are still in development. After the next CRAN update, they should all be stable, run on all operating systems, and talk to each other.
One other change coming down the pipeline is a "trilogy" package that first runs earthUI, then pipes its model into glmnetUI and mgcvUI, runs those two in parallel, and finally combines the output of all 3 into a final report.
journal.valuation-engineer.com has no public source other than the website itself. It will reference code on GitHub or CRAN as necessary. The indiviual articles will be backed up and separately registered on Zenodo in Geneva, Switzerland. The official release of the inaugural release is July 1, but it likely won't be officially released until about July 8. At that time, there will be more updates to some of the existing articles, and more additions, probably my paper on "Handling Latent Variables" and a paper on "Defining Neighborhoods". And then maybe some Editorial and so on.
I will likely add a forum to valuation-engineer.com as well. It will be strictly for discussions on valuation, coding and analysis. No political theater - you can always do that on. this forum.
Anyway, I have my CrossRef membership for DOIs and will be getting my ISSN for the Journal by July. So, it will be a complete, official journal, capable of being cited and appearing in academic indexes and so on.
.... This output journal is supposed to be PERFECT. But, likely nothing is perfect - and I am sure to appreciate legitimate feedback on errors or oversights.
