“…In the case of d = 2, we observe that this is a special case of the combinatorial central limit theorem (For more detail see Von Bahr (Von Bahr, B., 1976), Ho and Chen (Ho, S.T., 1978)). Under the finiteness of absolute third moment, Neammanee and Suntornchost (Neammanee, K. & Suntornchost, J., 2005) gave the uniform rate of convergence and obtained the rate 198 √ n . Recently, Neammanee and Rerkruthairat (Neammanee, K. & Rerkruthairat, N.) improve the constant to be 78.36.…”
