Results of R-Squared values for the relationship between the estimated area of the alignment zone and group size (<i>N</i>) with fixed interaction radius (<i>r</i>_<i>o</i>) in a bounded domain.

The R-Squared values here are very low, with the greatest (0.2104) accounting for only 21.04% of the observed variance. Hence linear regression is not performed for this particular set of analysis.
