he transformed data block generates a set of indexes into the data that is the same size as the data. This is done by independently sampling each entry of <code>boot_idxs</code> from <code>1:N</code>, using a discrete uniform distribution coded as a categorical random number generator with an equal chance for each outcome. If resampling is not done, the array <code>boot_idxs</code> is defined to be the sequence <code>1:N</code>, because <code>x == x[1:N]</code> and <code>y = y[1:N]</code>.</p>
