Correlations, computer herbicidal activity

Structure-activity correlations were carried out using least-squares regression analysis techniques on an IBM 360 computer. As in the accompanying publication (6), the data in Tables I and II were fitted to Equation 3 in stepwise fashion. Standard statistical tests were carried out at each stage of fitting to determine the over-all goodness of fit of the x and o- data to the various equational forms examined. As in our previous study (6), the most statistically significant correlations were always obtained when activity data for meta-substituted and para-sub-stituted TFMS herbicides were divided into two discrete series and fitted separately.
