 Applied Statistics
Using orientation statistics to investigate variations in human kinematics,
by D. Rancourt, L.-P. Rivest and J. Asselin,
Journal of the Royal Statistical Society Series C, Applied Statistics, Volume 49
(2000).
The data file for this paper has 720 rows and 8 columns. Missing values are coded as
NA.
column 1 gives the subject number (1-8)
column 2 gives the joint (1=wrist 2=elbow 3=shoulder)
column 3 gives the position as defined in Figure 2 of the paper (1-6)
column 4 gives the replicate number (1-5)
columns 5-8 give the quaternion for the rotation matrix characterizing the pose at the
joint. The quaternions S3-are unit vectors coded as (cos(a/2),u1 sin(a/2),u2 sin(a/2),u3
sin(a/2)) where a is the angle of the rotation and (u1,u2,u3) is a unit vector
representing the axis of the rotation.
