The inferential statistics variables are calculated as indicated below. To access these
variables for use in expressions, press 5 (5:Statistics), and then select the VARS
menu listed in the last column below.
df df (degree of freedom) represents (number of sample categories)
- (number of estimated parameters for the selected distribution +
1).
Xlist, Ylist The names of the lists containing the data for LinRegTTest and
LinRegTInt. Defaults are L1 and L2, respectively. The
dimensions of Xlist and Ylist must be the same.
RegEQ The prompt for the name of the Y= variable where the calculated
regression equation is to be stored. If a Y= variable is specified,
that equation is automatically selected (turned on). The default is
to store the regression equation to the RegEQ variable only.
