[R] Inverse function using FDA
Hi, Does anyone know how (or whether or not it's possible) to output an inverse of a functional object? I haven't found a way, but since derivatives etc. can be computed using the fda package it seems like this should be possible using this package or another designed for functional data analysis. Thanks, Zoe Richards [[alternative HTML version deleted]] __ 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.

Thanks, Zoe Richards What does your question mean? Possibly, you could 'invert' a mean function, but I have no idea what that would accomplish. Can you provide an example of just what you want to do?

I am trying to register unemployment rate and inverse of inflation rate to investigate the phillips curvehttp://www.econlib.org/library/Enc/PhillipsCurve.html by looking at the resulting warping function.
