[Rd] loess prediction algorithm

2007-07-26 Thread Benjamin Tyner
Andy, If you could provide an example of the R code with which you call loess(), I can post R code which will duplicate what predict.loess does without having to call the C/Fortran. There are a lot of implementation details that are easy to overlook, but without knowing the arguments to your call

The R interface is just a wrapper for those Netlib C/Fortran functions. I don't think anyone is going to be able (or willing) to read and explain those for you. You do need to understand the loess.control parameters, and I believe they are explained in the White Book. But perhaps you should use

Hello, I need help with the details of loess prediction algorithm. I would like to get it implemented as a part of a measurement system programmed in LabView. My job is provide a detailed description of the algorithm. This is a simple one-dimensional problem - smoothing an (x, y) data set. I
