Class MnMinos

java.lang.Object

org.freehep.math.minuit.MnMinos

public class MnMinos
extends java.lang.Object

API class for Minos error analysis (asymmetric errors). Minimization has to be done before and minimum must be valid; possibility to ask only for one side of the Minos error;

minos

public MinosError minos(int par)

minos

public MinosError minos(int par,
                        double errDef)

minos

public MinosError minos(int par,
                        double errDef,
                        int maxcalls)

Causes a MINOS error analysis to be performed on the parameter whose number is specified. MINOS errors may be expensive to calculate, but are very reliable since they take account of non-linearities in the problem as well as parameter correlations, and are in general asymmetric.

Parameters:

maxcalls - Specifies the (approximate) maximum number of function calls per parameter requested, after which the calculation will be stopped for that parameter.

range

public Point range(int par)

range

public Point range(int par,
                   double errDef)

range

public Point range(int par,
                   double errDef,
                   int maxcalls)

Causes a MINOS error analysis for external parameter n.

Returns:

The lower and upper bounds of parameter
