Fstat.fd

F-statistic for functional linear regression.

Fstat.fd calculates a pointwise F-statistic for functional linear regression.

Fstat.fd(y,yhat,argvals=NULL)

y

the dependent variable object. It may be:

yhat

The predicted values corresponding to y. It must be of the same class.

argvals

If yfdPar is a functional data object, the points at which to evaluate the pointwise F-statistic.

An F-statistic is calculated as the ratio of residual variance to predicted variance.

If argvals is not specified and yfdPar is a fd object, it defaults to 101 equally-spaced points on the range of yfdPar.

A list with components

`F`	the calculated pointwise F-statistics.
`argvals`	argument values for evaluating the F-statistic if `yfdPar` is a functional data object.
