TABLE II.

Linear Distances (LDs) for Which Error Due to Digitization is Greater Than 5% of the Total Variance Across all Scans and all Subjects

LD	MS_subject	MS_{scan(subject)}	MS_digitization	% error due to digitization
g-lex	98.98	2.95	5.61	5.2
g-ren	66.76	4.98	10.03	12.3
g-len	69.21	4.99	10.53	12.4
g-n	67.13	11.07	15.69	16.7
lgo-lch	142.22	17.35	8.74	5.2
lgo-lobi	308.55	17.68	20.03	5.8
rgo-robi	180.59	31.33	17.18	7.5

Columns 2, 3, and 4 show the mean squared error (MS) values for each error term. Column 5 shows the percentage of the total error that is due to digitization. For all LDs, between-subject variance was significantly greater than within-subject error variance (α=0.01). Landmark names are keyed to Table I and Figure 2.
