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
