Generate all valid combinations

dfs_parallel() computes all valid combinations of integers that match the given summary statistics.

Arguments

• mean - The mean of the target distribution.
• sd - The standard deviation of the target distribution.
• n - The number of elements in the target distribution.
• scale_min - The minimum value of the scale.
• scale_max - The maximum value of the scale.
• rounding_error_mean - The rounding error for the mean.
• rounding_error_sd - The rounding error for the standard deviation.

Returns

A vector of vectors, where each inner vector represents a valid combination of integers that matches the given summary statistics.
