TrendLinePolynomial(SeriesCollection,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.

   SeriesCollection sc,
   int degree
);

Parameters

sc

A collection of series objects. For example, to evaluate this indicator for two series you will need to pass a series collection containing this two 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).
