Error that varies in sign and magnitude from an observation to another.
1
Absolute precision error of percent fat measurements for the phantom ranged from 0.6 to 0.8%.
2
The long-term precision errors of other measurements were statistically the same as that of the spinal DXA.
3
Precision errors for volume were about 2-3% in the femur and 3-5% in the tibia.
4
Homogeneity parameters showed precision errors up to about 2% and anisotropy parameters up to about 4%.
5
Precision errors for BMD were about 1-2% lower.
