QuadReg [XList,YList,freq,Y]
-vCALC
Fits the second-degree polynomial (y=ax +bx+c) to
XList and YList with frequency list, freq, and stores
the regression equation to Y. 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 L1 and L2.
Decimal mode set to 2:
{1,3,4,5,5,7,8,9}

rand
seed Xrand
1PRB
Generates a random number between 0 and 1. By
storing an integer seed value (default=0) to rand, you
can control a random number sequence.

randInt(lower,upper[,#ofIntegers])
1PRB
Generates a random integer between lower and upper
(both integers) boundaries. To generate more than
one random integer, specify #ofIntegers, a positive
whole number>0.
