A simulated dataset for demonstrating ssm_analyze_long() and
ssm_plot_trajectory(). The data are simulated, not collected from people.
200 persons have scores on the eight octant scales at three waves. At each
wave the group profile is a cosine curve with elevation 0 and amplitude 0.6.
Its displacement
is 330 degrees at T1, 355 degrees at T2 and 20 degrees at T3, so the
profile crosses the 0/360 degree boundary between T2 and T3. Each person
has one offset, added to all eight scales at every wave, drawn from a normal
distribution with standard deviation 0.5. Each score also has its own noise,
drawn from a normal distribution with standard deviation 0.5.
Format
A data frame with 600 rows (one per person per wave) and 10 columns:
- id
Person identifier, 1 to 200.
- wave
Occasion, a factor with levels
T1,T2andT3in that order.- PA, BC, DE, FG, HI, JK, LM, NO
Scores on the eight octant scales, at the angles given by
octants().
Details
The data are written by a seeded script, data-raw/simulated_occasions.R,
which is not in the installed package. Read it on GitHub:
