Re: [Rd] loess prediction algorithm

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

Re: [Rd] loess prediction algorithm

The loess.demo function in the TeachingDemos package may help you to understand better what is happening (both running the demo and looking at the code). One common reason why predictions from the loess function and hand computed predictions don't match is because the loess function does an additi

[Rd] loess prediction algorithm

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
