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
|
m4 |
naive biased fourth central moment estimate m[4] = mean(c((X - X-bar)^4, (Y - Y-bar)^4)) for vectors
|
m6 |
naive biased sixth central moment estimate m[6] = mean(c((X - X-bar)^6, (Y - Y-bar)^6)) 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 fourth central moments μ[2] μ[4], where μ[2] and μ[4] are second and fourth central moments respectively.
