\r\n\r\nRecently I had some very noisy data that I wanted to fit a curve to. The problem is there were different regions that were somewhat linear, but the overall data was far from linear. A spline or a polynomial did not capture the behavior in a global sense. What I wanted was the ability to fit a line to each region. SLM does that right out of the box.\r\n\r\n\"\"<\/a>\r\n\r\n

\r\n\r\nI think it is very instructive to look at how this code was packaged up. There is a clearly labeled tutorial that was easy to scan looking for an example like what I wanted to do. All of the files have lots of comments. sometimes more comments that code I think. The files are named coherently so they make a nice package. These are all great things to make a package that other people can use.","protected":false},"excerpt":{"rendered":"
