Make scrambled Halton draws
Description
A function for creating scrambled Halton draws. The code is a translation of the [GAUSS](http://www.caee.utexas.edu/prof/bhat/FULL_CODES.htm) codes written by Professor Chandra Bhat. Note that the maximum number of dimensions for the scrambled Halton draws is limited to 16. This is because only permutations up to prime 16 are included in the permutation matrix. Extending to more than 16 dimensions can be achieved by including a different permutation matrix.
Usage
make_scrambled_halton(n_ind, n_draws, n_dim)
Arguments
n_ind |
Number of individuals in your sample |
n_draws |
Number of draws per respondent |
n_dim |
Number of dimensions |
Details
The permutations are based on the Braaten-Weller algorithm.
