Method Detail

compileCall

public Calc compileCall(ResolvedFunCall call,
               ExpCompiler compiler)

Description copied from interface: FunDef

Converts a call to this function into executable objects.

The result must implement the appropriate interface for the result type. For example, a function which returns an integer must return an object which implements IntegerCalc.

Specified by:

compileCall in interface FunDef

Overrides:

compileCall in class FunDefBase

debug

protected static void debug(String type,
         String msg)

process

protected static LinReg.Value process(Evaluator evaluator,
                   ListCalc listCalc,
                   DoubleCalc yCalc,
                   DoubleCalc xCalc)

accuracy

public static LinReg.Value accuracy(LinReg.Value value)

linearReg

public static LinReg.Value linearReg(List xlist,
                     List ylist)

forecast

public static List forecast(LinReg.Value value)
