LinReg(ax+b) [XList,YList , freq,Y
n
]
- v
C A L C
Fits the linear equation (y=ax+b) to XList and YList
with frequency list, freq, and stores the regression
equation to Y
n
. XList, YList, and freq (if specified)
must have the same number of elements.
freq is the frequency of occurrence for each
corresponding data point in XList. If freq is omitted,
all values are used once.
Defaults for XList and YList are
L 1
and
L 2
.
Decimal mode set to 2:
