TrendLinePolynomial(String,Series,Int32) Method

Fits a polynomial of a given degree to a data set in accordance with the least squares approach and returned the values of the fitted function over the same range of the x-coordinate as the given data set.

[Visual Basic]
Overloads Public Shared Function TrendLinePolynomial( _    ByVal seriesName As String, _    ByVal s As Series, _    ByVal degree As Integer _ ) As Series
[C#]
public static Series TrendLinePolynomial(    string seriesName,    Series s,    int degree );

Parameters

seriesName
The name of the series which will be displayed on the chart, i.e. its label.
s
A statistical series.
degree
The degree of the polynomial which is fitted to the data set given (i.e. if degree is 2, then a quadratic is fitted).

Remarks

For example, if we fit a polynomial of degree 2, then we fit the quadratic polynomial (i.e. f(x) = a_0 + a_1 x + a_2 x^2); similarly if we fit a polynomial of degree 3, then we fit the cubic polynomial (i.e. f(x) = a_0 + a_1 x + a_2 x^2 + a_3 x^3).
