Constructor Detail

StudyPolynomialRegression

public StudyPolynomialRegression()

Constructs a newly allocated StudyPolynomialRegression object

Method Detail

getCoefficients

public double[][] getCoefficients()

Returns the coefficients of the polynomial equation for each series.

getDegree

public int getDegree()

Gets or sets the degree of the polynomial.

See Also:

resetDegree

setDegree

public void setDegree(int value)

Gets or sets the degree of the polynomial.

Parameters:

value -

See Also:

resetDegree

evaluate

public double evaluate(int seriesIndex,
              double x)

Returns the value of the polynomial at a certain X value

If an X value is outside the visible range of the Chart area, then a value can still be calculated and will not cause an exception.

Retrieve the value of the Polynomial Regression line at 5 for the first series.

Parameters:

seriesIndex - The series to analyze.

x - The X Value.

getValue

public java.lang.String getValue(int series)

Description goes here

Specified by:

getValue in interface IStudy

Overrides:

getValue in class StudyLine

Parameters:

series -

resetDegree

public void resetDegree()

Set the property Degree to its default value.
