Generation of ordinal and continuous variables

Creates a data frame of discrete and continuous variables based on a latent correlation matrix and marginal proportions.

questionnaire_gen_family(
  n_obs,
  cat_prop,
  cov_matrix,
  family = "gaussian",
  theta = FALSE,
  mean_yx = NULL,
  n_cats
)

`n_obs`	number of observations to generate.
`cat_prop`	list of cumulative proportions for each item.
`cov_matrix`	covariance matrix. between the latent trait (Y) and the background variables (X and Z).
`family`	distribution of the background variables. Can be NULL or 'gaussian'.
`theta`	if `TRUE` will label the first continuous variable 'theta'.
`mean_yx`	vector with the means of the latent trait (Y) and the continuous background variables with flexible variance (X).
`n_cats`	vector with number of categories for each W.
