LinR
STAT CALC menu
Built-in equation variables
such as y1, r1, and xt1 are
case-sensitive. Do not use
Y1, R1, and XT1.
LinR xList , yList , frequencyList , equationVariable
Fits a linear regression model (y=a+bx) to real data
pairs in xList and yList and frequencies in
frequencyList
. The regression equation is stored to
equationVariable , which must be a built-in equation
variable such as y1 , r1 , and xt1 .
Values used for xList, yList, and frequencyList are
stored automatically to built-in variables
xStat , yStat ,
and fStat , respectively. The regression equation is
stored also to built-in equation variable RegEq .
LinR xList , yList , equationVariable
Uses frequencies of 1.
LinR xList , yList , frequencyList
Stores the regression equation to RegEq only.
LinR xList , yList
Uses frequencies of 1, and stores the regression
equation to
RegEq only.

LinR equationVariable
Uses xStat , yStat , and fStat for xList, yList, and
frequencyList , respectively. These built-in variables
must contain valid data of the same dimension;
otherwise, an error occurs. The regression equation is
stored to equationVariable and
RegEq .
