Spaceballs formulas

All stereological formulas

This equation does not include the terms F2 (area-fraction) and F3 (thickness-fraction) used by Mouton et al. (equation 2, 2002), but includes that information in v (volume sampled).

  • : Number of sections used
  • : Intersections counted
  • : Volume (grid X * grid Y* section thickness)
  • : Surface area of the sphere
  • : Section sampling fraction

  • : Intersection counted

,

  • : Variance due to noise
  • : Smoothness class of sampled function

  • : Variance due to SRS
  • : Variance due to noise

  • : Total variance
  • : Variance due to noise
