polyRoots(Poly,Var) ⇒ list
polyRoots(ListOfCoeffs) ⇒ list
The first syntax, polyRoots(Poly,Var),
returns a list of real roots of polynomial
Poly with respect to variable Var. If no real
roots exist, returns an empty list: {}.
Poly must be a polynomial in one variable.
The second syntax, polyRoots
(ListOfCoeffs), returns a list of real roots
for the coefficients in ListOfCoeffs.
Note: See also cPolyRoots(), page 40.
PowerReg
Catalog >
PowerReg X,Y[, Freq][, Category, Include]]
Computes the power regressiony = (a•
(x)
b
)on lists X and Y with frequency Freq. A
summary of results is stored in the
stat.results variable. (See page 172.)
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.
