	calculation of summary statistics. This value is based on
	the fit type chosen.
sCov	Contains the sample covariance of the current 2-variable
	statistical analysis (S1-S5).
σCov	Contains the population covariance of the current 2-
	variable statistical analysis (S1-S5).
ΣXY	Contains the sum of the X·Y products for the current 2-
	variable statistical analysis (S1-S5).
