|
m2 |
naive biased variance estimate m[2] =
mean(c((X - X-bar)^2, (Y - Y-bar)^2)) for vectors |
m3 |
naive biased third central moment estimate m[3] = mean(c((X - X-bar)^3, (Y - Y-bar)^3)) for vectors
|
m5 |
naive biased fifth central moment estimate m[5] = mean(c((X - X-bar)^5, (Y - Y-bar)^5)) for vectors
|
n_x |
number of observations in the first group. |
n_y |
number of observations in the second group. |
Pooled estimate of a product of second and third central moments μ[2] μ[3], where μ[2] and μ[3] are second and third central moments respectively.
