simulate_hier_dawid_skene_model | R Documentation |
Simulate data from the hierarchical Dawid-Skene model
simulate_hier_dawid_skene_model(pi, mu, sigma, sim_data, seed = NULL)
pi |
The pi parameter of the hierarchical Dawid-Skene model. |
mu |
The mu parameter of the hierarchical Dawid-Skene model. |
sigma |
The sigma parameter of the hierarchical Dawid-Skene model. |
sim_data |
Data to guide the simulation. The data must be in the long
data format used in
|
seed |
An optional random seed to use. |
The number of raters implied by the entries in the rater column must match the number of raters implied by the passed theta parameter.
The passed sim_data
augmented with columns:
"z"
containing the latent class of each item,
"rating"
containing the simulated rating.
J <- 5
K <- 4
