Interpretation of Components for Splines

["Peter M. Saama" <saama@pilot.msu.edu>]

Hello:

When we fit spl(t), and dev(day) in ASREML, the .asr file contains output
that looks like this:

   Source               Model  terms     Gamma                Component
Compnt/StndErr
  spl(time)                 18      18        6.65133
4.113614             1.41 P  
  dev(time)               20        20       0.603323E-01
0.103056E-02      0.47 P  
...

In the above table is 4.113614 a smoothing parameter or is it a variance
component? Furthermore, in the above table, is 0.103056E-02 a parameter
used in specification of the roughness penalty or is it a variance component?

Respectfully,

Peter M. Saama /
