Description: Sum of Squares of y-Values Command: Sums the squares of the values in the dependent-variable
columns of the current statistical matrix (reserved variable ΣDAT). The dependent column is the
column designated as YCOL

Type: Command
Description: Sum of Squares of y-Values Command: Sums the squares of the values in the dependent-variable

ΣY^2 is the same as ΣY2; see its listing for details.
Access:
YCOL
Type: Command
Description: Dependent Column Command: Specifies the dependent variable column of the current statistics
matrix (reserved variable ΣDAT).
The dependent variable column number is stored as the second parameter in the reserved variable
ΣPAR. The default dependent variable column number is 2.
YCOL will accept a noninteger real number and store it in ΣPAR, but subsequent commands that
utilize the YCOL specification in ΣPAR will cause an error.
