centroid_3d_sq_dist | R Documentation |
Calculates sum of squared point distances in 3D space betweeen points and their centroid.
\frac{
\sum_{i=1}^n (x_i-x_m)^2 + (y_i-y_m)^2 + (z-z_m)^2
}{
sum_(i=1)^n ((x - x_m)^2 + (y - y_m)^2 + (z - z_m)^2)
}
Where X/Y/Z
represent one axis each, a_m
represents the mean
of all points' coordinates on an axis, and n
represents the total
number of points.
