smooth.spline.pi0 {swfdr} | R Documentation

## Fit smoothing splines to several curves

### Description

This implementation uses smooth.spline. It gives a slight optimization by not reporting original data (keep.data=FALSE) and by setting numeric tolerance to a fixed number (tol=1e-7). In the latter, the precise number does not matter, but it is important that it is not computed from x at each iteration in the loop.

### Usage

    smooth.spline.pi0(x, ymat, df = 3)

### Arguments

`x` | numeric vector, position of knots
`ymat` | numeric matrix, ncol(ymat) should match length(x)

### Value

list with components pi0.smooth and pi0
