Hi all,
I have a series of intra-day data. The variables exhibit a typical daily pattern over the day. I need to diurnallly adjust the data. It takes the follow form 1, regress y on a piecewise cubic spline of x with knots (a1,a2,a3,a4...). x is the time of a day. 2, divide original series by the spline forecast. I know there are some functions to do the spline, like bs, splint, I do not know which one is exactly I need. Does anyway give me some suggestion? Thanks. -- View this message in context: http://r.789695.n4.nabble.com/How-to-generate-piecewise-cubic-spline-with-many-knots-tp3755419p3755419.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
