Hi all,
I'm trying to perform a functional linear regression with functional response
(comprising 14 coordinates) and 4 scalar covariates.
When I create a list containing the scalar covariates (with 14 replications
each), I keep getting the following message:
[1] "Vector in XFDLIST[[ 1 ]] has wrong length."
[1] "Matrix in XFDLIST[[ 1 ]] has more than one column."
[1] "Vector in XFDLIST[[ 2 ]] has wrong length."
[1] "Matrix in XFDLIST[[ 2 ]] has more than one column."
[1] "Vector in XFDLIST[[ 3 ]] has wrong length."
[1] "Matrix in XFDLIST[[ 3 ]] has more than one column."
[1] "Vector in XFDLIST[[ 4 ]] has wrong length."
[1] "Matrix in XFDLIST[[ 4 ]] has more than one column."
Error in fRegress.fdPar(PPIfdPar, predictor, betalist) :
problem with xfdlist
So in contrast to what is advised in the R FDA manual, I reduce my scalar
covariate matrices to column vectors with 88 rows (for 88 indepedent
observations), each. This message pops up:
[1] "Vector in XFDLIST[[ 1 ]] has wrong length."
[1] "Vector in XFDLIST[[ 2 ]] has wrong length."
[1] "Vector in XFDLIST[[ 3 ]] has wrong length."
[1] "Vector in XFDLIST[[ 4 ]] has wrong length."
Error in fRegress.fdPar(PPIfdPar, predictor, betalist) :
problem with xfdlist
Can anyone offer any solutions?
Many thanks in advance!
