I have a question about how to generate monthly data from quarterly data: What I want to do is basically fits cubic spline curves to the quarterly data to form continuous-time approximations of the input series, and then generate output series (monthly data) from the spline approximations.
SAS can do it using proc expand: http://support.sas.com/rnd/app/examples/ets/expa/ Anyone know how to do it in R? Any input is appreciated.
