 * Standardizes data using Mean Absolute Deviation (MAD) normalization.
 *
 * For each valid data point, applies the transformation: (x - mean) / mad

 * @example
 * ```ts
 * const data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
 * const standardized = await standardizeMAD(data);
 * console.log(standardized);
 * ```
 * @param data The numeric values to be standardized
 * @returns The standardized data using MAD normalization
