Function lattice_qcd_rs::statistics::mean_with_error_par_iter

pub fn mean_with_error_par_iter<'a, It: IndexedParallelIterator<Item = &'a f64> + Clone>(
    data: It
) -> [f64; 2]

Computes the mean the statistical error on this value a [rayon::iter::IndexedParallelIterator].

The statistical error is defined by sqrt(variance / len).

The alternative for iterators returning non-references is mean_with_error_par_iter_val.
