csch()
Catalog >
csch(Value1) ⇒ value
csch(List1) ⇒ list
Returns the hyperbolic cosecant of Value1
or returns a list of the hyperbolic cosecants
of all elements of List1.
csch⁻¹()
Catalog >
csch⁻¹(Value) ⇒ value
csch⁻¹(List1) ⇒ list
Returns the inverse hyperbolic cosecant of
Value1 or returns a list containing the
inverse hyperbolic cosecants of each
element of List1.
Note: You can insert this function from the
keyboard by typing arccsch(...).
CubicReg
Catalog >
CubicReg X, Y[, [Freq] [, Category,
Include]]
Computes the cubic polynomial regression
y=a•x
3
+b•x
2
+c•x+d on lists X and Y with
frequency Freq. A summary of results is
stored in the stat.results variable. (See page
145.)
All the lists must have equal dimension
except for Include.
X and Y are lists of independent and
dependent variables.
Freq is an optional list of frequency values.
Each element in Freq specifies the
frequency of occurrence for each
corresponding X and Y data point. The
default value is 1. All elements must be
integers ≥ 0.
Category is a list of numeric or string
category codes for the corresponding X and
Y data.
