The following Results variables store calculations from the
Statistics 2Var app. These calculations are performed
when is pressed in the Numeric view or the
Do2VarStats command is executed.
Corr Contains the correlation coefficient from the latest
calculation of summary statistics. This value is based on
the linear fit only, regardless of the fit type chosen.
CoefDet Contains the coefficient of determination from the latest
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).
