Abstract

Let n data x_1,x_2,…,_xn be [numerical formula](n is even). Minimize the function [numerical formula]|, then we get [numerical formula], median, Minimum value [numerical formula]. We call d Median Absolute Deviation. Let μ and σ^2 be the mean and variance, respectively, of n data x_1,x_2,…,x_n. Let μ_L and σ^2_L be the mean and variance, respectively, of lower group, n/2 data x_1,x_2,…,x_n/2. Let μ_U and σ^2_U be the mean and variance, respectively, of upper group, n/2 data [numerical formula]. Then We get [numerical formula].
