Point sampled intercept formulas
All stereological formulas
Volume based on intercept length (
)
- n: Number of intercepts
- l: Intercept length [Note that "l" is the intercept length through a cross section of the structure-of-interest. In the event that there is more than one intercept per cross section, l = intercept length plus twice the second intercept length (Gundersen and Jensen 1985, equation 6 and pg. 137, table 1).]
Volume-weighted mean volume (
)
- n: Number of intercepts
- l: Intercept length
Coefficient of error (CE)
- n: Number of intercepts
- l : Intercept length
Coefficient of variance (CV)
- n: Number of intercepts
- l: Intercept length
: Volume-weighted mean volume
Variance (VarianceV)
- L: Intercept length
: Volume-weighted mean volume
: Coefficient of variance
