Method Detail

getSimpleLinearRegression

public static RegressionStatistics getSimpleLinearRegression(ArrayList<Double> x,
                                                             ArrayList<Double> y)

Returns a simple linear regression.

Parameters:

x - the x series

y - the y series

Returns:

a simple linear regression

getRobustLinearRegression

public static RegressionStatistics getRobustLinearRegression(ArrayList<Double> x,
                                                             ArrayList<Double> y)

Returns a robust linear regression based on the median.

Parameters:

x - the x series

y - the y series

Returns:

a simple linear regression

getSimpleLinearRegressionOutlierRemoval

public static RegressionStatistics getSimpleLinearRegressionOutlierRemoval(ArrayList<Double> x,
                                                                           ArrayList<Double> y,
                                                                           Double p)

Returns a simple linear regression performed after outlier removal. If less than 100 points are available before or after filtering, a robust regression is used.

Parameters:

x - the x series

y - the y series

p - the probability for outlier exclusion, e.g. 0.95 for 95% confidence

Returns:

a simple linear regression
