vol.mse {pgs} | R Documentation |
Compute a MSE approximation for volume predictors. The structure of interest is an isotropic 3D random compact set. The sampling device is a uniform random lattice of figures (point patterns, line segments, sections...). The approximation depends only on sampling parameters and on the mean surface (to be provided) of the structure.
vol.mse(x, S = 1, L = 3)
x |
a lattice of figures, object of class FigLat-class. |
S |
the mean surface. Default: 1. |
L |
an integer, the criterion for stopping summation of the
Epstein zeta function. Argument of the function Ezeta . Default: 3. |
The MSE approximation as a numeric.
