In cds: Constrained Dual Scaling for Detecting Response Styles

Simulate Data for a Single Response Style

Description

Simulate data containing a single repsponse style.

Usage

datsim(
  nr.indv = 100,
  m = 5,
  scales = 1:7,
  err.coeff = 0.1,
  resp.style = c(-Inf, 1/7, 2/7, 3/7, 4/7, 5/7, 6/7, Inf),
  true.mu = NULL,
  a = 0,
  b = 1,
  plot.graph = FALSE,
  use.copula = FALSE,
  reverse.thresh = 1,
  ...
)

Arguments

nr.indv	Integer giving the number of individuals required in the sample.
m	The number of items.
scales	The rating scale used for all items.
err.coeff	The standard error used in simulating the truncated normal distribution.
resp.style	A set of cut points across the interval [0, 1] defining the response style transformation.
true.mu	Optional vector of length m giving the true preferences for the items.
a	Lower boundary of the truncation interval for the simulated true preferences.
b	Upper boundary for the truncation interval for the simulated true preferences.
plot.graph	Logical indicating whether to visualize the response style in a plot.
use.copula	Logical indicating whether to simulate dependent items using a copula.
reverse.thresh	A proportion giving the proportion of item preferences which should be reversed to induce a negative association.
...	Additional arguments passed to plot.
