An example

Description

A simulated dataset as an example

Usage

data(example)

Format

example is a list with six components (in the given order):

data.exp
data matrix with three columns: column 1–ID, column 2–measurement, column 3–time of measurement.
eigenf
true eigenfunctions: generated from cubic Bsplines with five equally spaced knots.
eigenv
true eigenvalues: first–1, second–0.66, third–0.52, others–zero.
M.tr
true number of basis functions: 5.
r.tr
true dimension of the process: 3.
sig.tr
true error standard deviation: 0.25.

Details

mean curve of the process is zero; principal component scores and errors are all i.i.d N(0,1); there are 200 subjects, and each has 2~10 measurements uniformly distributed on [0,1]; in total there are 1227 measurements
