, 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

MATH
min( (minimum) returns the smaller of two values or
the smallest element in one list. value can be a real
number, expression or a list.
If both values are lists, they must have the same
number of elements. If one value is a list and the
other a non-list, the non-list is paired with each
element of the list, and a list is returned.
