HP 50g Graphing, 48gII Graphing manual Ycol, …µΣY2

ΣY

Type:	Command
Description:	Sum of yValues Command: Sums the values in the dependent v ariable column of the current
	statistical matrix (reserved variable ΣDAT).
	The dependent variable column is specified by YCOL, and is stored as the second parameter in
	the reserved variable ΣPAR. The default dependent variable column number is 2.
Access:	…µΣY
Input/Output:
		Level 1/Argument 1		Level 1/Item 1
			→	Sum of Y

ΣY2	Command
Type:
Description:	Sum of Squares of yValues Command: Sums the squares of the values in			the dependentvariable
	columns of the current statistical matrix (reserved variable ΣDAT). The dependent column is the
	column designated as YCOL
Access:	…µΣY2
Input/Output:
		Level 1/Argument 1		Level 1/Item 1
			→	Sum of Y2

ΣY^2	Command
Type:
Description:	Sum of Squares of yValues Command: Sums the squares of the values in			the dependentvariable
	columns of the current statistical matrix. ΣY^2 is provided for compatibility with the HP 28.
	ΣY^2 is the same as ΣY2; see its listing for details.
Access:
YCOL	Command
Type:
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.
