Fabric intensity and shape indices
Value
numeric vector containing the fabric shape and intensity indices:
P
Point (Vollmer 1990). Range: (0, 1)
G
Girdle (Vollmer 1990). Range: (0, 1)
R
Random (Vollmer 1990). Range: (0, 1)
B
Cylindricity (Vollmer 1990). Range: (0, 1)
C
Cylindricity or Fabric strength (Woodcock 1977). Range: (0,
Inf
)I
Cylindricity or Fabric intensity (Lisle 1985). Range: (0, 5)
D
"Distance" from uniformity, linear from R to P, and R to G (Vollmer 2020). Range: (0, 1). End members are: uniform D = 0, girdle D = 0.5, cluster D = 1. The 99% level for a test against uniformity for a sample size of 300 is D = 0.1.
