A common interface to creating a variety of random draws used to simulate the log likelihood function
make_draws(n_id, n_draws, n_dim, seed, type)Number of individuals in your sample
Number of draws per respondent
Number of dimensions
A seed to change the scrambling of the sobol sequence.
A character string indicating the type of draw: "pseudo-random", "mlhs", "standard-halton", "scrambled-halton", "standard-sobol", "scrambled-sobol"
A matrix of dimensions n_id*n_draws x n_dim of standard uniform draws
n_id <- 10
n_draws <- 5
n_dim <- 3
draws <- make_draws(n_id, n_draws, n_dim, seed = 10, "scrambled-sobol")
#> Warning: scrambling is currently disabled.
