cos

public final static Double cos(Angle angle)

doLinearRegression

public final static Pair<Double, Double> doLinearRegression(List<Double> x, List<Double> y)

Does a linear regression of the form y = mx + b.

doLinearRegressionNoIntercept

public final static Double doLinearRegressionNoIntercept(List<Double> x, List<Double> y)

Does a linear regression of the form y = mx.

epsilonEquals

public final static Boolean epsilonEquals(Double $self, Double other)
