ΣY

Type: Command

Description: Sum of y-Values Command: Sums the values in the dependent variable 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.

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

ΣY^2

Command

 

 

Type:

 

 

Description:

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

 

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.

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.
